SIGNAL TRANSDUCER DEVICES, SYSTEMS, AND METHODS
First Claim
1. A signal transduction device comprising:
- a support element;
an electrically insulated electric circuit connected with the support element;
a piezoceramic sensor connected with the support element, the piezoceramic sensor configured to transmit a signal to the electric circuit; and
an integral protective coating provided on the piezoceramic sensor and having properties of mechanical strength and temperature resistance, the integral protective coating comprising;
a main body comprising an electrically insulating material, andan element comprising a thermally insulating material, the element connected with the main body and being in contact with the support element at a region substantially perimetrally surrounding the piezoceramic sensor, the element configured to direct a predetermined portion of an external compression force acting on the signal transduction device onto the region of the support element substantially perimetrally surrounding the piezoceramic sensor.

Abstract
Various braking devices, systems, and methods are disclosed. In some embodiments, the braking device includes a support element, a block of friction material supported by the support element, at least one piezoceramic sensor supported by the support element and interposed between the block of friction material (and the support element, and a protective element located at the piezoceramic sensor and embedding the latter. The protective element can have one or more layers of resin-based material applied to protect the piezoceramic sensor and direct a predetermined part of the external compression force onto an area of the support element surrounding the piezoceramic sensor. In some embodiments, a signal transduction device is provided and includes at least one piezoceramic sensor supported on a support element and has an integral protective coating having properties of mechanical and temperature resistance.
