Abstract :
This paper contains a design of miniature proximity sensor used in the my electric prosthetic hand to perceive the approaching distance of grabbing objects. An infrared sensor is used as a probe in this sensor which adopts the principle that the infrared reflects the light intensity. The compact structure of the sensor can make it suitable for a fingertip of a prosthetic hand. There is a modulation-demodulation part added up to its signal processing circuitry to obtain the stable output signal filtered and amplified by the modulation-demodulation, the voltage of the signal will change according to the proximity distance. The result of the experiment shows that the sensor has strong anti-jamming ability, and it is very competent for the my electric prosthetic hand.
