This course dives into the fundamental principles of transduction — the process of converting one form of energy into another. Whether it's mechanical to electrical, thermal to digital, or biochemical to electronic, transduction lies at the heart of modern biomedical devices, robotics, wearable tech, and intelligent systems.
You’ll explore how biological and artificial systems sense, respond, and interact with the physical world. From nerve impulses to smart sensors, this course connects physics, biology, and engineering through the lens of energy conversion.
