For the first time, scientists have created a flexible programmable chip that is not made of silicon. The new ultralow-power 32-bit microprocessor from U.K.-based Pragmatic Semiconductor and its colleagues can operate while bent, and can run machine learning workloads. The microchip’s open-source RISC-V architecture suggests it might cost less than…

Stretchy Circuits Break Records for Flexible Electronics

Computer & Information Technology

Newly developed intrinsically stretchable circuits are thousands of times as fast as and possess 20 times as many transistors as previous intrinsically stretchable electronics. The researchers at Stanford University who developed the circuits have already demonstrated their use in a skin-like Braille-reading sensor array that they say is more sensitive…

Mesh Wearables Meld Micro Sensors and LoRa Smarts

Electrical, Electronics & Instrumentation, Mechanical, Production & Manufacturing

As healthcare wearables for various medical conditions and situations proliferate, patients inevitably want their wearable tech as inconspicuous and worry-free as possible. As a case in point, consider a new wearable mesh health-monitor that does away with the “box and a strap” architecture that is still the industry’s de facto…

Supercapacitors Get Smaller Than Ever

Electrical, Electronics & Instrumentation

As smart devices, wearable sensors, IoT technologies, and implantable electronics shrink in size, so too should the energy-storage devices they rely on. Supercapacitors—with high capacity for energy storage but also a capability to handle rapid charge-discharge cycles that would founder a conventional chemical battery—have in recent years shrunk to “micro”…
