Title: **Marc C. Foote: Pioneering Innovation in Thermoelectric Sensors**
Introduction
Marc C. Foote is an innovative inventor based in La Crescenta, California, renowned for his contributions to the field of thermoelectric sensors. With a total of two patents to his name, Foote's work has significantly advanced the capabilities and applications of micromachined thermoelectric devices.
Latest Patents
Marc C. Foote's most recent patents focus on micromachined thermoelectric sensors and arrays. His work on linear arrays includes up to 63 micromachined thermopile infrared detectors on silicon substrates. Each detector is comprised of a suspended silicon nitride membrane featuring 11 thermocouples made from sputtered bismuth telluride (Bi–Te) and bismuth-antimony telluride (Bi–Sb–Te) thermoelectric films. Demonstrating exceptional performance, these detectors achieve response times of 99 milliseconds, zero frequency D* values of 1.4 × 10^9 cmHz^1/2/W, and responsivity values of 1100 V/W when analyzing a 1000 K blackbody source. Notably, the only significant source of noise noted above 20 mHz is Johnson noise originating from the detector resistance. These findings represent the best performance reported thus far for thermopile detector arrays, making them particularly suitable for uncooled dispersive point spectrometers. Additionally, Foote's research has led to the development of detector arrays with D* values reaching as high as 2.2 × 10^9 cmHz^1/2/W and response times of 83 ms.
