A piezoelectric device has a piezoelectric element (2) with an electrically conductive surface and an electrical terminal (1) spaced from that surface with a resilient, compressible mass of electrically conductive material (9) held captive between the terminal (1) and that surface to form an electrical connection therebetween. Typically, the electrically conductive material (9) comprises filaments, such as brass wire wool, having at least a conductive surface layer and which are resilient in bending so that when compressed they tend to expand and maintain continuous physical and electrical contact with the adjacent restraining surfaces. The low inertia of the resilient filaments and their multiple contact with the adjacent surfaces helps provide the required continuous contact. Thus, the use of a conventional soldered connection to the piezoelectric element and the associated stress related mechanical failure problems or physical access problems are avoided.
