IoT start-up Psikick has received US$16 million ($22.8 million) in Series B financing from new and existing angel investors.

The company said in a statement that the latest funding round was led by Osage University Partners and included existing investors New Enterprise Associates (NEA), the University of Michigan Investment in New Technologies Fund (MINTS) and several individuals.

Psikick makes “self-powering” wireless sensor technology. It uses a combination of energy harvesting from ambient radiofrequency sources and low-power electronics to underpin its technology platform.

“This Series B financing will allow us to continue hiring leading IoT engineering talent and developing completely batteryless systems based on these fundamental technologies,” CEO Brendan Richardson said.

UK start-up Drayson Technologies is similarly developing IoT technology that is powered by harvested energy.
