Patent number: 8006564Abstract: The present invention relates to a method of determining both pressures and temperatures in a high temperature environment. The present invention also relates to a method of determining temperatures about a pressure-sensing element using a bi-functional heater. In addition, the present invention preferably relates to a pressure sensor with the pressure-sensing element and a heating element both integrated into the sensor's packaging, preferably onto the diaphragm of the pressure sensor, and particularly to such a pressure sensor capable of operating at high or elevated temperatures, and even more particularly to such a pressure sensor wherein the heating element is capable of both heating, at least in part, the pressure-sensing element and monitoring the temperature of the application area. Preferably, the pressure-sensing element is formed from shape memory alloy (SMA) materials that can be used at high or elevated temperatures as a pressure sensor with high sensitivity.Type: GrantFiled: August 11, 2009Date of Patent: August 30, 2011Assignee: Orbital Research Inc.Inventors: Greg S.

Patent number: 6622558Abstract: A method and sensor for detecting strain using shape memory alloys is disclosed. The sensor comprises a substrate material, a flexible diaphragm provided on the substrate material and a thin film SMA material deposited on the flexible diaphragm. The thin film SMA material is capable of undergoing a phase transformation in response to a physical stimulus being applied thereto. During such a phase transformation, a change occurs in the electrical resistance of the thin film SMA material. By measuring the value of the electrical resistance of the thin film SMA material immediately before and after the thin film SMA material undergoes a phase transformation, the difference in the value of the electrical resistance can be determined and utilized to determine the magnitude of the physical stimulus that was applied to the thin film SMA material causing it to undergo a phase transformation.Type: GrantFiled: November 30, 2000Date of Patent: September 23, 2003Assignee: Orbital Research Inc.Inventors: Michael A.
