In this research, the organic piezoelectric sensor, which was originally in the form of a film, was made into a cable. Although this new application is expected, it has the problem that it is difficult to identify the position of the applied pressure when a piezoelectric response signal is generated in response to external pressure. Therefore, in order to identify the pressurized position of the cable from the signal obtained from a single cable, we improved the internal structure of the cable and the signal measurement circuit, and applied the corresponding algorithm for identifying the pressurized position, and succeeded in identifying the position.
