Power/Performance Bits: April 27


Energy-harvesting shirt Engineers at the University of California San Diego developed a 'wearable microgrid' that harvests and stores energy from the human body to power small electronics. The microgrid consists of three main parts: sweat-powered biofuel cells, motion-powered triboelectric generators, and energy-storing supercapacitors. All parts are flexible, washable and can be screen pri... » read more

Power/Performance Bits: April 20


Multiplexing twisted light Researchers from University of California San Diego and University of California Berkeley found a way to multiplex light by using discrete twisting laser beams from antennas made up of concentric rings. "It's the first time that lasers producing twisted light have been directly multiplexed," said Boubacar Kanté, an Associate Professor at UC Berkeley's Department ... » read more

Harvesting body heat Researchers at University of Colorado Boulder, Harbin Institute of Technology, Southeast University, and Huazhong University of Science and Technology designed a stretchy thermoelectric generator that can be worn against the skin to power small wearable electronics using body heat. The stretchy material polyimine is used as the base of the device. A series of thin therm... » read more

Power/Performance Bits: Jan. 19


Electronic skin for health tracking Researchers at the University of Colorado Boulder developed a stretchy electronic 'skin' that can perform the tasks of wearable fitness devices such as tracking body temperature, heart rate, and movement patterns. "Smart watches are functionally nice, but they're always a big chunk of metal on a band," said Wei Zhang, a professor in the Department of Chem... » read more

Versatile Thin‐Film Transistor with Independent Control of Charge Injection and Transport for Mixed Signal and Analog Computation


Source: University Of Surrey: Eva Bestelink Olivier de Sagazan Lea Motte Max Bateson Benedikt Schultes S. Ravi P. Silva Radu A. Researchers at University of Surrey and Université de Rennes developed a new device, called a Multimodal Transistor (MMT), that is immune to parasitic effects. In the MMT, on/off switching is controlled independently from the amount of current passing th... » read more

Computational Software


Electronics technology is evolving rapidly, becoming pervasive in our lives. There are more smart phones in use than there are people on earth, driver assistance is now common in automobiles, commercial airplanes have increasingly sophisticated infotainment, and wearable health monitors exist for a plethora of missions. Every device is generating and communicating massive amounts of data, inclu... » read more

Power/Performance Bits: Sept. 22


Drawing sensors on skin Researchers from the University of Houston and University of Chicago created an ink pen that can draw multifunctional sensors and circuits directly on skin. These "drawn-on-skin electronics" aim to provide more precise health data, free of the artifacts that are associated with wearable devices and flexible electronic patches. Caused when the sensor doesn't move prec... » read more

Startup Funding: July 2020


A number of semiconductor and design companies took in funding this month, from a mega round for a data center switch maker to seed grants for two Canadian companies and new funding for an IP marketplace. China continues to be a hot area for electric vehicles, with one company raising half a billion for its two models currently in production. For July, we highlight fifteen startups that raised ... » read more

Power/Performance Bits: June 30


Up-converting lasers Researchers at the University of Pennsylvania developed a filter chip that can convert the output from low-cost lasers to have the same frequency noise as big, expensive lasers, making them suitable for applications such as LiDAR. The noise in a laser's frequency is an important indicator of quality. Low-quality, noisy lasers have more random variations, making them use... » read more

Power/Performance Bits: June 23


Capturing waste heat Researchers at Wuhan University and University of California Los Angeles developed a hydrogel that can both cool down electronics and convert the waste heat into electricity. The thermogalvanic hydrogel consists of a polyacrylamide framework infused with water and specific ions. When they heated the hydrogel, two of the ions (ferricyanide and ferrocyanide) transferred e... » read more
