Abstract:
The invention concerns a novel bulk acoustic wave (BAW) resonator design and method of manufacturing thereof. The bulk acoustic wave resonator comprises a resonator portion, which is provided with at least one void having the form of a trench which forms a continuous closed path on the resonator portion. By manufacturing the void in the same processing step as the outer dimensions of the resonator portion, the effect of processing variations on the resonant frequency of the resonator can be reduced. By means of the invention, the accuracy of BAW resonators can be increased.

Abstract:
A device (100) harvests energy from vibration and/or strain and utilises both capacitive (102a, 102b) and piezoelectric elements(105). The principle of operation is out-of-plane capacitive harvester,where the bias voltage for the capacitive element is generated with a piezoelectric element(105). The device utilizes a thin dielectric film (104) between the capacitor plates (102a, 102b) maximizing the harvested energy and enabling the harvester operation in semi-contact mode so that short circuits are prevented. For example when utilised in a wheel or the like, the capacitor is closed and opened at every strike or every turn of a wheel being thus independent of the harvester's mechanical resonance frequency.
