Piezoresistive Pressure Sensor Design and Optimization- Group 1

Introduction
This project focuses on designing and optimizing a piezoresistive pressure sensor using modern microfabrication techniques. Piezoresistive sensors are devices that measure changes in pressure by detecting changes in electrical resistance. The sensor will be developed using MEMS (Micro Electro Mechanical Systems) technology, which allows the creation of small, highly precise sensors on silicon chips. MEMS technology is widely used due to its ability to integrate mechanical and electronic components on a single chip. The design process will involve creating 3D models, running simulations, and performing tests to ensure that the sensor works accurately under various pressure conditions. This approach helps in understanding the mechanical behavior of the sensor and optimizing its design before actual manufacturing.
Motivation
Accurate pressure measurement is crucial in many applications, such as aerospace, automotive systems, and industrial processes. Traditional pressure sensors may lack the required sensitivity, accuracy, or stability under different conditions, making them unsuitable for high-precision tasks. By developing a piezoresistive pressure sensor using, we can achieve a small, efficient, and highly sensitive device that performs reliably even under changing temperature and pressure. This project provides an opportunity to learn sensor design, understand how pressure affects sensor behavior, and optimize sensor performance through 3D modeling and simulation. It also helps students develop skills in theoretical research and practical testing.
