Power/Performance Bits: March 8


Non-toxic, printable piezoelectric Researchers at RMIT University and University of New South Wales developed a flexible and printable piezoelectric material that could be used in self-powered electronics including wearables and implantables. "Until now, the best performing nano-thin piezoelectrics have been based on lead, a toxic material that is not suitable for biomedical use," said Dr N... » read more

Fast-charging EV battery Electric vehicle adoption faces challenges from consumers' range anxiety and the extended lengths of time needed to charge a car's battery. Researchers at Pennsylvania State University are trying to address this by developing lithium iron phosphate EV batteries that have a range of 250 miles with the ability to charge in 10 minutes. It also is expected to have a lifeti... » read more

Programmable photonics Researchers from the University of Southampton developed a method for making programmable  integrated switching units on a silicon photonics chip. By using a generic optical circuit that can be fabricated in bulk then later programmed for specific applications, the team hopes to reduce production costs. "Silicon photonics is capable of integrating optical devices and... » read more

Thinner, flexible touchscreens Researchers from RMIT University, University of New South Wales, and Monash University developed a thin, flexible electronic material for touchscreens. The material is 100 times thinner than current touchscreen materials. The new screens are still based on indium-tin oxide (ITO), a common touchscreen material. However, a liquid metal printing approach was used... » read more

Designing metamaterials Sandia National Laboratories has developed an inverse-design software technology that automates the design of optical metamaterials. Metamaterials are artificial materials containing arrays of metal nanostructures or mega-atoms. Some metamaterials are able to bend light around objects, rendering them invisible. But they only interact with light over a very narrow ran... » read more

Modeling computer vision on human vision University of Michigan scientists used digital foveation technology to render images that are more comprehensible to machine vision systems, while also reducing energy consumption by 80%. The effect is achieved by manipulating a camera’s firmware. “It'll make new things and things that were infeasible before, practical,” Professor Robert Dick s... » read more

Sensing without battery power Engineers at the National University of Singapore developed an IoT-focused sensor chip that can continue operating when its battery runs out of energy. The chip, BATLESS, uses a power management technique that allows it to self-start and continue to function under dim light without any battery assistance. The chip can operate in two different modes: minimum-ene... » read more

Waste heat to power Engineers at the University of California, Berkeley, developed a thin-film system that can be applied to electronics to turn waste heat into energy. The thin-film system uses pyroelectric energy conversion, which is well suited for tapping into waste-heat energy supplies below 100 degrees Celsius, called low-quality waste heat. In particular, the technology might be part... » read more

Giant thermometer The Department of Energy's Oak Ridge National Laboratory has devised a new way to take the temperature of a material at the nanoscale—the organization has developed a giant thermometer. The technology, dubbed electron energy gain spectroscopy, enables researchers to take the temperature of a material from an area at about a billionth of a meter wide. Developed by Nion, t... » read more
