Tactile sensors

Definition

Tactile sensors are devices that detect and measure physical interactions, such as pressure, texture, and vibration, through direct contact with objects. They play a crucial role in providing feedback to robots or systems, allowing them to interact more effectively with their environment. By mimicking the sensory capabilities of biological organisms, tactile sensors enable advancements in bio-inspired soft actuators and sensors, facilitating smoother and more adaptive movements.
