An applied electric field is used to control the piezoelectric action of a thin-film Aluminum Nitride resonator and toggle the switch open or closed. These switches have a demonstrated reliability of 10^7 cycles and a resistance of 500 Ohm, which makes them suitable for logic circuits. The polarity of the switch can be inverted by applying the electric field to different electrodes of the same switch, making complementary action (p-type and n-type) possible with the same device. This low power alternative to CMOS could offer important advantages for miniaturization and reduced power consumption.
