Contrary to FPW sensors that use progressive waves at the resonance, we use standing waves on our mechanical structures which allow us to obtain higher integration density. 4×4 matrixes of piezoelectric membranes use PbZr xTi1-xO3 (PZT) as piezoelectric film which geometries have been drawn by lift-off techniques. Each membrane (circular shaped, with a radius equal to 150 microns) can be individually addressed for actuation and/or sensing. Here we show that the same kind of membranes exhibit excellent self-sensing capabilities by using the direct piezoelectric effect of the PZT layer. The open-loop resonant frequencies of several membranes were measured by examining the self-induced charge on the sense electrode using a proximity electronics circuit. We simultaneously performed resonant frequencies measures by means of a dynamic optical interferometer that completely matched the electrical self-sensed resonant spectra. In this case the piezoelectric membranes were actuated in two different ways, either by using an external transducer or by using the self-actuating (reverse piezoelectric effect) capability of each membrane.Show less >
