An Antenna Sensor to Identify Finger Postures

This paper proposes one of the sensor combine with an antenna to execute double function for sensor and communication as a wireless sensor. In order to decrease signal distortion and to improve data rate by omitting some ports. The as-made sensor was test at a center frequency of 81 MHz for measuring human finger postures using principle of dipole antenna. The results showed that the motion sensor operates accurately in identifying finger angles at 0°, 45° and 90°.
