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.

for high dynamic range shear and normal force sensing," J.
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.
The topics include the atomic-layer deposition of thin inorganic coatings into renewable packaging materials, developing woven enhanced silk fabric for ballistic protection, novel piezoelectric tactile sensor
materials with improved properties, enhancing the char resistance of expandable graphite-based intrumescent fire retardant coatings by using multi-wall carbon nano tubes for structural steel, developing new sol-gel surface treatments formulation for the bonded repair of aircraft, and the laminated microstructure and toughness mechanism of abalone shell.
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.
based on piezoelectric resonance (in PZT ceramic) is used in robotics (Krishina & Rajanna, 2004).
Pressure Profile Systems has introduced its Industrial Tactile Sensor
(ITS), a user configurable sensor designed to quantify high pressure measurements in industrial and elevated temperature environments.
