Aryabhata writes "As per a BBC article, US scientists have created a device that could one day pave the way for robotic hands mimicking human touch. The research team from University of Nebraska in Lincoln hopes to apply this to aid surgery by allowing surgeons to feel the tissue they are operating on. This could help surgeons in distinguishing cancerous or abnormal tissue etc. To demonstrate the device the scientists tried the instrument on a one cent coin and the sensor revealed the wrinkles in President Lincoln's clothing and the letters TY in liberty."
