摘要： Piezoelectric polymer film, when conformably adhered to inner or outer curved surfaces of an inflated balloon, for example, acts as a speaker when the metallized coatings of the film are suitably connected to the output of an audio device. The film may be in the form of an helical strip, or individual strips elastically serially connected, or may itself form the inflatable material. Amplifying and impedance matching means may be interposed between the audio output and film coatings.

摘要： Piezoelectric polymer film transducers include a metallized film electrode deposited on each of the two surfaces of the film. The electrodes are provided with leads extending therefrom in staggered parallel relationship. Each lead of the improved connector is associated with a reinforced assembly comprising plastic strips, a terminal connector, optional spacer washers, and a metal rivet penetrating the assembly such that electrical contact is effected between the lead and terminal connector. To insure positive electrical contact, a conductive ink may be deposited on one of the plastic strips through which an orifice is provided. The orifice communicates with a selected lead. The ink coats walls of the orifice to insure electrical continuity between the lead and terminal connector. A modified connector assembly disposes the reinforced connectors beyond the edges of a substrate which carries or supports the piezoelectric polymer film transducers.

摘要： A traffic sensor including piezoelectric sensors having different polarities in different lanes of the roadway so that traffic data for different lanes of a roadway may be discriminated from the polarity of the received signal(s). Preferably, the piezoelectric sensors are formed by splicing oppositely polarized piezoelectric cables or films, by changing the applied electric field during manufacture so that adjacent portions of a piezoelectric cable or film have different polarities, or by applying an electric field of a reversed polarity to respective longitudinal sections of a piezoelectric film. Traffic data from up to 8 different lanes of traffic may be discriminated using only two piezoelectric sensors in accordance with the invention by providing unique combinations of output polarities for deflections of the piezoelectric sensors in the different lanes. In order to simplify installation, such piezoelectric sensors may be disposed in parallel within the same housing or concentrically within the same cable.
