Abstract :
The batteryless accelerometer which follows "ISO 15693 13.56 MHz radio frequency identification (RFID)" has developed with MEMS acceleration sensor which can detect plusmn2G. 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. But a conventional flat loop antenna has the limitation in the direction because it cannot send and receive radiowave when it isn\´t oriented parallel with an antenna of a RFID reader. We have developed a 3D loop antenna which can communicate in any triaxial direction.
