Block Patterning of the Metallization of Polyvinylidene Fluoride Transducers.
Abstract
There is disclosed herein a composite sheet used as a transducer for producing voltage in response to intercepted mechanical or thermal stimuli. The composite sheet comprises a sheet such as polyvinylidene fluoride (PVDF) having at least one of piezoelectric and pyroelectric properties sandwiched between a plurality of thin film conductive blocks arranged in block patterns to establish there between a network of sensors. The composite sheet may be used to wallpaper a room for securing it against intrusion. The composite sheet provides transducer output with improved frequency response over a similar sized transducer without the block patterning. Electric shorting between opposed blocks does not interfere with voltage production in other areas of the composite sheet. Patent applications. (jhd)
