POLYURETHANE ELASTOMER PIEZOELECTRIC ELEMENT, PRESSURE- SENSITIVE SENSOR AND CONTACT SENSOR

摘要

PROBLEM TO BE SOLVED: To provide a piezoelectric element composed of a polyurethane elastomer, and a pressure-sensitive sensor and a contact sensor which have the piezoelectric element. SOLUTION: This polyurethane elastomer piezoelectric element is characterized in that the polyurethane elastomer into which a fullerenol is introduced is installed. It may be possible that polyurethane elastomer into which the fullerenol is introduced has a film type form. The pressure-sensitive sensor and the contact sensor are characterized in that the polyurethane elastomer piezoelectric element is used as a piezoelectric element. COPYRIGHT: (C)2004,JPO
