PIXEL

This project aims to develop advanced pMUT ultrasonic transducers and arrays (functional demonstrator) for gas flowmeters for flow measurement in transportation and energy-related applications.

Project Objectives

The main objective is the development of advanced pMUT arrays for gas flowmeters from concept to prototype

Advanced pMUT arrays will enable the gas flowmeters to work in harsh conditions.

Further research efforts:

  • The frequency shift caused by the pressure variations will be compensated, e.g., the center frequency can be shifted from 300 kHz to 200 kHz.
  • The bandwidth of advanced pMUT arrays will be improved to 50 %.
