Researchers have designed a millimeter-sized sensor that has many of the tactile abilities of a human finger: it can sense the magnitude and the position of an applied force, slippage of a grasping tool, and the softness of an object, such as a cancerous tumor. The engineers have designed the sensor to be compatible with the grasper of many minimally invasive surgery (MIS) tools, as well as to be easily fabricated by Microelectromechanical Systems (MEMS) techniques.
