The broader impact/commercial impacts of this Small Business Technology Transfer (STTR) Phase I project is in a range of fields, which includes electric vehicle technology, advancing geolocation capability, and improving efficiency of industrial processes. A high temperature pressure sensor will be developed. The sensor’s material layers will be designed to optimize sensitivity, refine the device and manufacturing process to enhance performance, and develop a durable package capable of withstanding high temperatures. Once fabricated, the sensors will undergo rigorous testing under varying pressure and temperature conditions to ensure reliability and effectiveness. This design can directly replace current silicon-based sensors. These new sensors will be packaged and tested at industrial partner’s high-temperature facility. The project activities will create extensive training opportunities for PhD students and internship opportunities for students visiting from the university partner and other nearby colleges/ universities. This Small Business Technology Transfer (STTR) Phase I project focuses on the unmet market need for reliable pressure sensors operating at high temperatures, where traditional silicon (Si) piezoresistive pressure sensors are unsuitable. To meet this market need, a circular membrane-based pressure sensor made of wide bandgap semiconductors, will be developed, which can operate at high temperature due to their wide bandgap suppressing thermal carrier ge
