looking for tactile sensors

[limor]

I'm looking for tactile sensor options. This is what i came by so far:

capacitive surface sensing, they seem to provide a touch sensitive matrix within various flexible mats of different sizes. Used by WillowGarage PR2

The FlexiForce sensor acts as a force sensing resistor in an electrical circuit. When the force sensor is unloaded, its resistance is very high. When a force is applied to the sensor, this resistance decreases.

The SynTouch BioTac contains the three sensory modalities found in the human fingertip: force, vibration, and temperature. These allow the sensor to do things that humans are able to do with touch, such as:

Determine point of contact
* Estimate tri-axial forces
* Detect slip
* Estimate the radius of curvature of a contacted object
* Sense initial contact with an remarkably high sensitivity
* Discriminate edges, corners, and flat surfaces
* Discriminate textures
* Discriminate object compliance
* Discriminate objects based on their thermal properties

QTC™ Material has the unique ability to smoothly change from an electrical insulator to a metal-like conductor when placed under pressure. While in an unstressed state the QTC™ Material is a near-perfect insulator; with any form of deformation the material starts to conduct and with sufficient pressure metallic conductivity levels can be achieved.
