| Abstract | We report on the development of a novel technique for creating real-time frequency tuning in Piezoelectric Micromachined Ultrasound Transducers (PMUTs). This technique employs controlled virtual added mass in a confined microfluidic environment as a switch to tune the resonant frequency of a PMUT. Using this technique, we could vary the frequency of a |
