The companies have developed a WPT power receiver development kit using a combination of NGK’s lithium-ion rechargeable batteries EnerCera, TOREX’s low-current-consumption power supply ICs and Ossia’s WPT technologies.
Conventionally, powering IoT devices involved power cables and primary batteries (disposable batteries), so cumbersome wiring and replacing batteries had been an issue.
Using radio frequency (RF) to transfer power over about 10 meters, WPT is attracting attention as a power supply technology that promotes the realization and widespread use of maintenance-free IoT devices as it enables power supply to places where wiring presents difficulties and eliminates the need to replace batteries.
In particular, Ossia’s Cota WPT using the 5.8 GHz band is expected to be used in a wide range of applications, including power supplies for sensors installed in places such as enterprise environments, retail, factories and warehouses.
A am At the higher frequency of 5.8GHz, it enables smaller receivers and more precise control of power supply.
