Triboelectric generator mimics seaweed to extract electricity from waves

Triboelectric nanogenerators (TENGs) could extract energy from waves large and small, even well under water, according to Chinese scientist. The seaweed-like proof-of-concept generators were ~40 x 80mm, and attached at one end to somethign solid while currents in the water wafted the free end. They were made by coated two strips of different polymers with conductive ...

MCUs to meet BLE 5.3

Renesas is developing new MCUs that will support the recently released Bluetooth 5.3 Low Energy (LE) Specification. The new devices will be part of the Renesas Advanced (RA) Family of 32-bit Arm Cortex-M microcontrollers, joining the RA4W1 Bluetooth 5.0 LE device introduced last year. Renesas expects to have first samples of the new MCUs in the ...

Clamping diodes for USB4

Nexperia is aiming at protecting USB4 with a pair of semiconductor clamping chips – effectively back to beck Zeners, but built around active silicon-controlled rectification. “Since there are tight budgets on insertion loss and return loss for the USB4 Super Speed lines, Nexperia is offering devices that minimise the impact of ESD protection on the ...

Flash price to ease

NAND contract prices are expected  drop 0-5% QoQ in 4Q21 as demand slows, according to TrendForce. Suppliers are likely to downsize their capacity expansion activities for 2022, resulting in a 31.8% YoY increase in bit supply next year. Annual bit demand, on the other hand, is projected to increase by 30.8% YoY. YoY growth of ...
