Abstract	Wireless power delivery to electronic objects scattered over tables, walls and ceilings will form an infrastructure necessary for ubiquitous electronics, wireless sensor networks and ambient intelligence. Described here are design innovations to overcome the shortcomings of a previous wireless power transmission sheet [1] made with plastic MEMS switches and organic FETs (OFET) circuits suitable for printable low-cost electronics. The sheet delivers power to multiple objects, frees the users from position adjustment, reduces the number of coil arrays, and takes 5V dig-ital input by using a newly developed level shifter. The principle of wireless power transmission is based on an array of coils (TX-coil) made on a plastic sheet, which is selectively driv-en by plastic MEMS switches and is coupled magnetically with a receiver coil (RX-coil) mounted on a power receiving object as shown in Fig. 20.4.1. The MEMS switch can transfer amperes of
