High-quality film production for next generation devices

ULVAC Inc. has announced the successful launch of PZT piezoelectric thin-film sputtering technology and a high volume manufacturing (HVM) solution to solve technical issues that have hindered the development of MEMS devices, which are crucial in applications from autonomous driving to next generation wearable terminals (such as smart glasses). The company has begun selling production systems incorporating the new technology. Evolutions in technologies such as 5G and AI are expected to accelerate the journey towards smart societies, in which the digitisation of all types of industries will improve industrial performance and enhance convenience for people. With increasing levels of multi-functionality found in autonomous driving, AR/VR, security, and smartphone applications, actuators are needed in order to activate devices based on signals received from various types of sensors. Demand for actuators is projected to explode and key issues in their development have come to the fore, including the need for miniaturization, reduced production costs, lower power consumption, and higher performance. It used to be impossible to fabricate PZT piezoelectric thin films, which constitute the key technology in sensors and actuators, using a low-temperature process with the conventional coating method (Sol-Gel). However, in 2015, ULVAC successfully developed the world’s most advanced technology for forming PZT piezoelectric thin films using a low-temperature sputtering process. ULVAC has continued developing this as next-generation MEMS technology. By further advancing this proprietary technology, ULVAC has reduced running costs by optimizing system operation and has greatly improved the technology’s reliability, which is critical for device commercialization. The result is a groundbreaking mass-production technology that is now incorporated into systems ULVAC has begun to sell. This technology allows MEMS devices to be integrated with semiconductors (CMOS), and enables other positive outcomes such as miniaturisation, reduced production costs, lower power consumption, and higher performance. It is expected to pave the way […]

Collaboration results in interleaving veils for composite toughening

New Zealand company, Revolution Fibres, has collaborated with Mitsubishi Gas Chemical Company, Inc. to develop a next-generation nanofiber interleaving veil for improving the toughness of carbon fibre composites. The new nanofibre veil material, called Xantu.Layr XLB, has particularly strong application possibilities in the aerospace sector. Xantu.Layr XLB is made from Mitsubishi’s recently developed XD10 thermoplastic, bio-based polyamide resin, LEXTER. LEXTER is a xylylenediamine-derived polyamide resin that has been demonstrated successfully as a thermoplastic matrix for composite materials. It is tough, strong, and chemically resistant, and has the added benefits of being hydrophobic and highly compatible with epoxy resin when in the form of a nanofiber veil. These properties enable Xantu.Layr XLB nanofibre interleaving veils to improve the performance of thermoset composite laminates without being compromised by exposure to high humidity, gasoline or a range of other chemicals. Another benefit of this new nanofibre veil is the lower cost of manufacture, resulting in a lower sale price. Dr. Nobuhiko Matsumoto, a Research Manager at Mitsubishi Gas Chemical, said that they “were thrilled to see LEXTER in the form of a nanofiber veil and could see many commercial possibilities for applications.” Xantu.Layr is produced using a proprietary production method (Sonic Electrospinning Technology), and is an ultra-thin non-woven web consisting of kilometre long thermoplastic nanofibres, with each one around 500 times thinner than a human hair. When placed in-between the plies of carbon fibre in a composite laminate, Xantu.Layr significantly improves the fracture toughness (delamination resistance), compression after impact strength (damage tolerance) and fatigue resistance of the composite without adding any significant thickness and weight. Xantu.Layr nanofibre veils can improve composite materials by providing nano-scale reinforcement of the brittle matrix resin, resulting in a tougher resin (even when used with already toughened resin systems) which is less prone to micro-cracking when stressed or […]

Smart technologies can improve safety in the oil and gas industry

By Gaurav Sharma, Head of Industries Business, ANZ, Cognizant Employee safety remains a key concern within the oil and gas sector. The nature of tasks and activities makes it a riskier industry than others. Workers’ fatigue is another factor increasing that risk. However, the oil and gas industry is in a prime position to take advantage of technologies such as robotics, wearables, artificial intelligence (AI) and machine-learning (ML) to minimise some of the risks, as well as drive innovation. The risks of fatigue Fatigue is a major contributor to safety incidents in the oil and gas industry. An oil and gas worker’s job includes inherently risky routine and physically demanding tasks such as positioning heavy equipment, climbing on scaffolds, and physical inspections and maintenance. Characteristics specific to the oil and gas industry are also factors increasing that risk, such as fly-in fly-out and shift work conditions, dealing with time zone changes and 24/7 operations, handling hazardous chemicals or working in extreme weather conditions. Research indicates that the injury rate of Australian shift workers is two times higher than other workers, due to fatigue-related factors such as insufficient sleep, disrupted sleep patterns, and extended working hours. Using digital technologies to predict fatigue risk There is an increasing awareness across risky industries that digital technologies have an important role to play in improving work safety. Leading oil and gas providers are now looking to improve their current standards even further through data collection, monitoring, and automation. However, there is still a long way to go to full adoption, as estimates suggest that just one percent of the data currently captured by operators is being used for improvement purposes. These technologies can provide companies with better control on workplace hazards and better training, while improving onsite communications and overall workforce and business asset […]

200 kilometres in eight minutes: powering the e-mobility revolution

What started as a small start-up in one of ABB’s business units almost a decade ago is now an integral part of the company’s innovative push for sustainable mobility. One innovation after another is coming from ABB developments in electric-vehicle (EV) chargers. The Terra HP is the world’s fastest EV-charger, adding up to 200 kilometres of range to an electric vehicle in just eight minutes. With the number of electric vehicles on the road rising, the global demand for powerful and energy efficient vehicle charging stations is ever increasing. ABB EV-chargers, like the Terra High Power charger, are the driving force behind the efforts of nations to reach sustainability targets and charges have become a critical part of sustainability policies. With more than 7,000 DC fast charging stations installed in 60 countries, ABB is a global leader in that segment. The technology behind e-mobility is truly coming of age, which is also shown in ABB’s partnership with the ABB FIA Formula E Championship. ABB is bringing its name, innovation and technology leadership to the first fully electric motor sport series. The ABB FIA Formula E Championship perfectly supports ABB’s belief that we can run the world without consuming the earth. The series’ next race will be in Zurich on June 10. The ascendance of sustainable mobility and the charging infrastructure required to keep electric vehicles moving is evident by the increasing number of ABB EV charging projects around the world. German energy supplier EnBW alone has 185 EV fast chargers on German motorways and in April, ABB was selected to supply its Terra HP charging stations as part of the biggest electric vehicle infrastructure project to date in the United States. The chargers were selected for deployment by Electrify America, which plans to place hundreds of charging stations within and around 17 […]

3D printing of human heart

Scientists in Israel have unveiled a 3D print of a heart with human tissue and vessels, a first and a “major medical breakthrough” that advances possibilities for transplants. Scientists hope one day to be able to produce hearts suitable for transplant into humans as well as patches to regenerate defective hearts. The heart produced by researchers at Tel Aviv University is about the size of a rabbit’s. It marked “the first time anyone anywhere has successfully engineered and printed an entire heart replete with cells, blood vessels, ventricles and chambers. People have managed to 3D-print the structure of a heart in the past, but not with cells or with blood vessels. But the scientists said many challenges remain before fully working 3D printed hearts would be available for transplant into patients. Journalists were shown a 3D print of a heart about the size of a cherry, immersed in liquid, at Tel Aviv University as the researchers announced their findings, published in the peer-reviewed journal Advanced Science. Researchers must now teach the printed hearts “to behave” like real ones. The cells are currently able to contract, but do not yet have the ability to pump. Then they plan to transplant them into animal models, hopefully in about a year. Maybe, in 10 years, there will be organ printers in the finest hospitals around the world, and these procedures will be conducted routinely. However, hospitals would likely start with simpler organs than hearts.

Researcher creates ‘smart silicone’ that reacts to heat and light

Wellington nanotechnology researcher Andreas Zeller has created new techniques to make high value smart elastic silicone by incorporating nanocrystals and quantum dots. The smart elastomers have a wide range of commercial applications from smart bandages that change colour when they need changing, to soft robots for delicate surgical manipulation, to eco-friendly paints that could control their environment by absorbing or reflecting heat depending on the season. Dr Zeller started his Emerging Innovator project to identify the beach-head application for the ‘smart silicone elastomer’ technology as a Research and Development Scientist at the MacDiarmid Institute at Victoria University of Wellington. He is continuing his research project in his new role as a member of Callaghan Innovation’s Microfabrication Team, with ongoing support from the MacDiarmid Institute and Principal Investigator, Professor Thomas Nann. “Silicone is an important material as it is biologically inert, highly elastic, optically transparent and easily moulded. Its excellent properties lend it to widespread and diverse applications from lab-on-a-chip devices for point of care diagnostics to solar cells and holographic displays,” says Dr Zeller. “I’ve taken this silicone a step further by adding nanocrystals and quantum dots to add photochromic and thermochromic characteristics, which means it has new high value function as it can react to heat and light.” Silicone functionalised with photochromic nanoparticles responds quickly to UV light as a reversible reaction darkens the film, which naturally returns to normal over time. “So thin photochromic silicone film could, for example, be used as UV and sun protectant on windows,” says Dr Zeller. To create colour changing silicone that responds to changes in temperature, Dr Zeller has added thermochromic nanoparticles. “Thermochromic functionalised silicone has a diverse range of potential applications including smart industrial seals that signal if a device is overheating and medical devices that give feedback as to when […]

Demand for higher quality parts and products to drive generative design

Generative design enables the design of lighter, cheaper components while maintaining strength and solidity, ultimately creating a higher quality product. For that reason, the adoption of generative design software is taking off in aerospace and defence, automotive, footwear and clothing, furniture, industrial machines, and oil and gas industries and leading to an uptick in engineering throughput in each of them, finds ABI Research, a market-foresight advisory firm providing strategic guidance on the most compelling transformative technologies. “The rise of the sharing economy and additive manufacturing will drive both demand for and the ability to produce higher-quality goods,” explained Pierce Owen, Principal Analyst at ABI Research. “Generative design expands design possibilities by creating shapes different from those that humans would create. It idealizes the design by creating something that best fits the constraints to optimise the products for various requirements.” For several years now, industrial companies have used geometric topology optimisation – eroding the geometric shape of a product given a set of constraints to improve performance – and are using it more as the use cases for additive manufacturing have increased. Generative design takes that another step by creating, or generating, the geometric shapes from an engineer’s requirements rather than changing existing shapes. Also, unlike topology optimisation, generative design creates many iterations, variations and/or alternatives for engineers to compare, rather than simply removing unnecessary pieces or particles. Additive will drive both generative design and topology optimisation as it provides greater build freedom to fulfill a wider variety of designs. Traditional Computer-Aided Design (CAD) vendors such as Dassault Systèmes, Siemens and recently, PTC, already have or will have embedded generative design capabilities within their CAD environments as plug-ins or kernels. PTC acquired Frustum in November 2018 to do exactly that within Creo. Several of Siemens products, including NX, NX Nastran, HEEDS, […]
