Design for Mixed Circuits of Organic FETs and Plastic MEMS Switches for Wireless Power Transmission Sheet

Design innovations to overcome the shortcomings of a wireless power transmission sheet made with plastic MEMS switches and OFET for printable low-cost electronics are shown. The mixed circuits of MEMS switches and OFETs with two different frequencies reduce the number of coil sheets form 2 to 1. OFET level-shifters, with the current-source loads with enhancement/depletion mixed threshold voltages realized by controlling the back-gate voltage, bridge the operation voltage gap between silicon VLSIs (below 5 V) and OFETs/MEMS (above 40 V).
