Powercast unveils printed medical wearables
At CES 2022 in Las Vegas this week, Powercast is highlighting its RF wireless power technology in a 3D – printed wearable monitor which can be used by both out-patients at home and athletes to monitor their biomedical signals. The flexible monitor was developed by researchers at the University of Arizona.
Battery management IC monitors can shrink final form factors
Charge and fuel gauge accuracy in a smaller solution size can be realised with the MAX17330 by Analog Devices. It includes AccuCharge technology with integrated fuel gauge and battery protection for one-cell lithium-ion/polymer batteries to extend battery runtimes.
MEMS timing accelerates wireless charging says SiTime
For power-sensitive and space-constrained mobile and IoT applications, the SiT3901 uPower digitally controlled MEMS oscillator (DCXO) has been introduced by SiTime. It improves wireless charging speed by up to 25 per cent while reducing the overall timing solution area by up to 90 per cent, says the company. The MEMS oscillator is suitable for wireless charging systems for smart watches, activity trackers, hearing aids, and wearables.
