Development of an Algorithm for a PZT Ceramic Foot Pressure Sensor
Currently available foot pressure sensors (FPS), which usually include a capacitive sensor and a piezoresistive sensor, tend to exhibit characteristically slow response times. Therefore, we used PZT (lead zirconate-titanate) ceramic in this study, as it responds more quickly than the currently-used materials. We have developed an algorithm which can be applied to the PZT ceramic-based measurement of foot pressure. This algorithm was also verified in experiments. In this study, we fabricated the electronic circuits and a sensor on the basis of the newly-developed algorithm, and then verified the algorithm experimentally.
