Write short notes on Tactile Sensor.

A tactile or fingertip force sensor measures forces generated during physical contact or pressure with the environment. This sensor mimics the human sense of touch, which responds to mechanical stimulation of the skin. Tactile sensors are widely used in robotics, computer hardware and security systems. A significant challenge in robotics is achieving finger dexterity, which limits the ability of conventional robotic systems to perform complex manual tasks effectively.
