To charge low power applications, such as hearing aids and other wearable devices that require resistance to water and dust, Renesas has developed the RAA457100 power receiver IC and a power transmitter IC (the RAA458100). Each includes all the functions needed for wireless charging on a single chip. An evaluation kit is also available.

PMIC uses proprietary technique for energy harvesting
Using proprietary energy management technology, the AEM10940 PMIC comprises a low power boost converter (at 94 per cent efficiency levels), voltage reference, energy management and LDO regulator elements. Its cold-start circuitry enables it to be brought into active operation even when there is minimal energy left, says e-peas. An input voltage of 380mV and just 11microW of power are more than sufficient, it adds.
Small MEMS oscillators boast lowest power operation
MEMS oscillators from Microchip, the DSC6000 family, are claimed to be the smallest in the industry and with the lowest power consumption over 2.0kHz to 100MHz.
Mouser stocks the Intel Curie module for wearable devices
Distributor Mouser Electronics is making wearable development more accessible, by stocking the Intel Curie module.
