Patent number: 5369995Abstract: A humidity sensor device which utilizes a humidity-sensitive piezoelectric polymer film as a transducer element. In a preferred embodiment a pair of excitation electrodes and a pair of pickup electrodes are provided on such a polymer film, a suitable excitation voltage is applied to the excitation electrodes and the resultant transverse piezoelectric effects are detected in the form of an electrical output voltage from the pickup electrodes. The electrical output signal is converted to the humidity value of the gaseous environment based on a prior calibration. Typically, an odd nylon such as nylon-11 or nylon-7 is used for the piezoelectric element and a rectangular, uniform and porous graphite films are deposited thereon as electrodes. The humidity sensor device of this invention can be used over a wide temperature range and can withstand repeated exposure to harsh temperature conditions over a long period of time.Type: GrantFiled: April 21, 1993Date of Patent: December 6, 1994Assignee: Rutgers, The State University of New JerseyInventors: Jerry I.

Patent number: 4349502Abstract: Fabrication of unoriented phase I crystalline PVF.sub.2 is described wherein commercially available PVF.sub.2 phase II (crystalline form) is placed in a high pressure cell and its temperature is raised slightly over its melting point. The sample is then subjected to abrupt changes in high pressure and the temperature is dropped thereafter. The pressure is then reduced resulting in a product which contains both phase I and phase II forms of PVF.sub.2. The phase I content of the product varies from a few percent and up depending upon the pressure applied during the quenching step.Type: GrantFiled: October 24, 1980Date of Patent: September 14, 1982Assignee: The United States of America as represented by the Secretary of the NavyInventors: Kook D.
