Characterization of polymer-based piezoelectric micromachined ultrasound transducers for short-range gesture recognition applications

The Interuniversity Microelectronics Centre investigated the use of polymer-based piezoelectric micromachined ultrasound transducers (PMUT) for short-range gesture recognition applications
During the course of the project the optical microphone was used to measure the pressure emitted by a single PMUT at various distances
