WISP is one such computer that can prove that IoT is indeed the future for mankind.
Its a tiny computer that doesnt need a battery.
They got rid of the battery to make WISP that much smaller.
so that function, the WISP gathers energy from a standard radio frequency identification, or RFID reader.
From there its able to generate enough electricity to do low-key processing tasks like keeping track of sensor information.
While WISP is battery free it doesnt have that much charge as a normal battery charged computer.
It could also be used as a sensor in fitness wearables and medical implants that track a patients health.
Sensor Lab researchers have recently made WISP powerful enough to run some decent practical applications.
WISP isnt the first battery-free sensor of its kind.
That said and done, WISPs battery-free and wireless charging feature is a breakthrough.
