Micro-convertor with remotely coupled DC power international conference on control, automation and systems (ICCAS 2014)

Microsystems are rapidly making their avenue into commercial applications. Power needs to be supplied to individual devices without requiring wires or physical tethering if the full potential of the micro-machines are to be realized. We develop direct DC power for micro-devices using remote radio-frequency (RF) generation as well as on-chip RF to DC micro-convertor. The micro-scale antennas will supply as much as 10 mW of DC power in an area less than 20mm × 20mm. Optical coupling may not be required because the RF energy can be penetrated into the system without significant loss of energy through media. Fabrication of working remotely powered micro-chips is being developed. This technology may realize power convertor for individual micro-robots, micro-probes as well as wireless power distribution to multi-chips and micro-scale energy storage devices such as batteries.
