Abstract: A sensor (10) preferably capable of high resolution sensing over a large operating range includes a composite diaphragm (12) containing nanotubes or nanowires (14). The nanotubes or nanowires (14) preferably form a mat that is embedded in insulating material (16, 18), such as high dielectric or insulating thin films. The nanotubes or nanowires (14) may provide the diaphragm (10) with a Young's modulus of greater than about 1000 GPa and a tensile strength of greater than about 100 GPa. The strain in the nanotubes or nanowires (14) may be measured by a change in resistance, voltage, current or capacitance.

Abstract: An industrial thermoelectric generation assembly (100) and method (200) are provided. A plurality of thermoelectric generation elements (104) is provided. Each element has a first side, a second side opposite the first side, and a lateral surface. A thermally insulative material (102) surrounds the lateral surface of each thermoelectric element (104). The first side of each thermoelectric element is disposed to contact a process heat source (106), and the second side is configured to be exposed to an ambient environment. At least two of the plurality of thermoelectric generation elements (104) are wired in series. The thermoelectric generation elements (104), being good thermal insulators, provide good thermal insulation to the process. Withholding heat within the process (which is desired), is converted to electricity.

Abstract: Pressure and mechanical sensors include a sensing component formed of a titanium and tantalum alloy having an elastic (Young's) modulus of less than about 80 GPa and a tensile strength of greater than about 1,000 MPa. The high strength and low elastic modulus, together with very low temperature dependence of the elastic modulus and very low linear thermal expansion, result in high resolution and precise measurement over a large temperature range.
