Batteryless Accelerometer Using Power Feeding System of RFID

The batteryless accelerometer which follows "ISO 15693 13.56 MHz radio frequency identification (RFID)" has developed with MEMS acceleration sensor which can detect plusmn2G and has discrete circuit devices including micro processing unit (MPU) and thermistor. This module utilizes the radiowave for power feeding and signal communication as RFID. And therefore, the cables for power supply and signal transmission and the battery as a power supply are not required. The range of radiowave transmission is 1 cm and 3D antenna is utilized to emit and to perceive radiowave to and from any direction
