Reducing the footprint of a hearable device, such as an ear bud, by using smaller batteries can come at the cost of shorter runtimes between recharges, advises Dialog Semiconductor. Hearable devices frequently read data to support advanced functionality such as connectivity, auto-pairing, charge cradle data exchange and equalisation. Dialog Semiconductor has developed the AT25SL128A Flash to minimise power consumption. It features low power, 1.8 V operation, fast read, low profile wafer level chip scale packages (WLCSPs) and is intended for small IoT devices like hearables.

InnovationLab and Evonik partner for printed rechargeable batteries
Printed electronics specialist, InnovationLab has partnered with chemical company, Evoknik to develop the fully printed, flexible, rechargeable, solid-state batteries. The batteries, which combine Evonik’s TAeTTOOz printable battery materials and InnovationLab’s high-speed printed electronics capability results in thin printed batteries that are more flexible, safer and more environmentally friendly than traditional metal-based batteries.
Boost converters and LDO have industry’s IQ says Maxim
For use in consumer, industrial, healthcare and IoT devices, the MAX17227A and MAX17291 boost converters and the MAX38911 LDO shrink the size of battery-operated devices and extend battery life for efficient power, says Maxim Integrated.
