Instrumentel Ltd., a U.K. company founded to develop a way to monitor moving engine pistons, says it is developing passive 13.56 MHz RFID tags capable of powering sensors and actuating switches as well as holding data. The company claims its prototype tags harvest significantly more power from its readers than other RFID systems operating in 13.56 MHz. Source: RFID Journal
