Abstract: A device (100) harvests energy from vibration and/or strain and utilizes 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 utilized 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.

Abstract: A micromechanical sensor for measuring millimetric wave or microwave power, which sensor comprises a wave line for conducting the millimetric or microwave power and a part arranged to move and a fixed electrode, in such a way that the capacitance (C) between the part that is arranged to move and the fixed electrode couples to the wave power advancing in the wave line. According to the invention, the capacitance (C) between the part that is arranged to move and the fixed electrode is divided into at least two portions (C/n), which are located at a distance from each other, in such a way that the wave power advancing in the wave line couples to the portions (C/n) of the capacitance (C) consecutively and experiences the inductive load between the portions (C/n) of the capacitance (C). Thus the frequency band of the sensor can be substantially broadened and the reflective coefficient can be kept reasonably small.
