Traditionally, tactile sensor designs have focused on sensing individual modalities: normal forces, shear forces or vibration exclusively.
Now, more accurate, stable and repeatable capacitive based tactile sensor arrays are available which measure a wide range of pressure values over areas of interest.

The tactile sensor array of this technique is intended to sense a wearer's actions via the force application and regional pressure variation when a human gets in contact with the auxiliary device, but without the influences of physiological disturbances, skin resistance and muscle fatigue.
A NEW TYPE OF TACTILE sensor that is nearly as sensitive as human skin may one day enable robots to do something humans take for granted-casually wrap their fingers around a cup of coffee without looking.
Washington, April 19 ( ANI ): Researchers at the Harvard School of Engineering and Applied Sciences (SEAS) have developed a very inexpensive tactile sensor for robotic hands that is sensitive enough to turn a brute machine into a dextrous manipulator.

Honda has developed a highly functional compact multi-fingered hand, which has a tactile sensor and a force sensor imbedded on the palm and in each finger, respectively, and which acts to control each finger independently.
A camera is focused on the tactile sensor so the operator can see the tactile probe as it moves about the part, providing, for example, the means to visually verify the interaction of the stylus and the workpiece.
Another tactile sensor working with 'holograms is the airborne ultrasound tactile display being developed at the University of Tokyo, Shinoda Lab.
