Abstract: An acupuncture pen comprises: a casing (11); a blunt tip (13), provided at the front end of the casing moveably; a sensing unit (12), provided in the casing (11) for detecting the movement of the tip (13); An A/D converter (15), provided in the casing (11) for converting the analog signal from the sensing unit (12) into digital signal; a microcontroller (16), provided in the casing (11) for receiving the digital signal from the A/D converter (15), and calculating the force blunt tip (13) applied on the skin on the basis of the received digital signal; and a digital display, provided in the wall of the casing, and electrically connected with the microcontroller (16) for indicating the calculated force. With such structure, the acupuncture pen of this invention can achieve compact configuration and indicate the force applied by the pen visually.
