Sensors

Definition

Sensors are devices that detect and measure physical properties and convert them into signals that can be read and interpreted by observers or systems. They play a critical role in bioengineering by enabling the collection of data about biological processes, physiological states, and environmental conditions, allowing for improved monitoring, diagnostics, and treatment in healthcare and medical devices.
