While tactile sensors were heralded in the late 1980s as the major development of the coming decade, there was a downward trend that followed. However, with advancement in robotics and computing, tactile sensing has made a comeback. A tactile sensor is basically able to detect changes in parameters like shape, texture, temperature, vibration, shear/normal forces and touch. One of the important modern usages of tactile sensing is in the domain of biomedical applications and systems for unstructured environments. Many times a current sensor is relied on for such a project and these sensors are later adjusted as per the system requirement.
