Capacitive Sensors: Part I

This lecture covers the principles of capacitive sensors, focusing on single capacitor applications such as microphones. It explains the relationship between surface area, distance, and permittivity in sensor sensitivity. The lecture also delves into the functioning of microphones, including the measurement of sound through capacitor vibrations. Furthermore, it explores the transfer function of capacitive sensors and their applications in devices like digital stethoscopes and cochlear implants.
