碩士 === 國立臺北科技大學 === 機電整合研究所 === 101 === Plantar pressure/shear force array sensor are placed at the bottom of the shoe-pads. When user walks with them, the soles of shoes touch the ground. The Sensing unit perceives different level of pressure and adopts a set of four sensors to detect the Shear force direction. The analog signal is transformed to digital data through the microprocessor in the circuit. The digital signal will then be transmitted to mobile phones or computers through wireless transmission by bluetooth module. As a mobile phone or a computer receives the data, it shows the corresponding position of the foot on the APP. The color which displays on the mobile or computer changes from light to dark with the different perceived level of pressure and represents the current plantar pressure situation of user. Besides, the APP calculates the center of gravity of user according to the numerical value and position of the 16 Sensing unit and it is presented by red star.
