Inspired by the human cochlea, we propose a directional sound sensor using a resonator array to overcome the limitations of existing directional microphones. The proposed sensor consists of multiple cantilevers that respond to different resonance fre

We have proposed a new type of electrostatic actuator for optical switching which has trench structure to make low voltage driving possible. Its lower or fixed electrode consists of a horizontal electrode and an extra vertical one which acts as a sto

We measured the characteristics of free space type 16/spl times/16 micro optical switches. Two types of micro mirrors to switch the laser beam were used. One is electrostatic actuation type and the other is mixing (electromagnetic+electrostatic) type

We demonstrate that reduced graphene oxide (rGO) coated thin aluminum film is an effective optoacoustic transmitter for generating high pressure and high frequency ultrasound previously unattainable by other techniques. The rGO layer of different thi
