In this course, students will learn the basic sensing theory behind of the wearable and implantable sensing technology. A variety of advanced sensors will be introduced, including temperature/humidity, pressure, acceleration, gyroscope, motion, heartbeat, sweat, impedance, ultrasonic, UV, optical, electrochemical and biomedical sensors. In the class, students will design and propose a concept of their own unique wearable and implantable device/system using multiple sensing techniques. Recent and future trends in wearable and implantable sensor technology will be discussed too. Students will gain a broad perspective in the area of sensors and wearable and implantable technology for healthcare and appealing applications.
