A touch sensor that captures what we feel when we apply force because its response curve is close to human perception of force. Contact pressure provides smooth continuous control. Responds to pressure from approx. 1 KPa (10 g/cm2, 0.1 PSI) to 2.5 MPa (25 Kg/cm2, 355 PSI) or a force of approx. 0.1 N (10 g, 0.02 lb) to 0.20 KN (20 Kg, 44 lb) that's applied evenly across its active area, a disk with 10 mm (0.4 inch) diameter. View, calibrate, record and map the sensor data using our TouchSensors software (see below).

And look it's part of a family of touch sensors. Here are it's relatives (note that all these sensors have a less smooth response curve):

Application examples

  1. Can be easily worn or applied to a variety of flat surfaces. Blow Laurie Anderson, Marillion and others away. Trigger those samples!
  2. Measure your weight distribution on a platform or tile. See the BalanceTile demo !
  3. Use as a touch sensor for a sound synthesizer.
  4. May be used to design your own fretless base. Use for capturing slaps while the Slide-500 functions as your pitch controller. A GForce3D-6 will help you accentuate your tones when you move the stem upright.
  5. Can be used in your custom wind instrument design. Use for buttons, while using a Slide-170 for octave control and a GForce3D-6 to capture body movements.
  6. Create a fancy control panel by combining Push sensors (Push, Push2D), Reach sensors (Reach, ReachClose, ReachOn), Slide sensors (Slide-50, Slide-170, Slide-500, SlideRound, SlideWide), Touch sensors (see above and TouchMiniOn) and Turn sensors to name a few.

Application notes
  1. Please note that calibration of the sensor requires careful attention to detail since they behave differently near the extremes of the usable range. The sensor behaves as a force sensor within the specified range but may not behave like a force sensor beyond this range. It is merely documented as a saturation effect above the range, meaning that sensitivity changes with force, and as a threshold effect below the range, which behaviour may be hard to repeat or even random.
  2. To obtain reliable results, the force has to be applied evenly across the active surface area of the sensor. Using a finger to calibrate or to measure how much force you exert is very unreliable unless you at least use a flat rigid object between the finger and the sensor.
  3. If the sensor shows a non-zero value when no force is applied, flatten the sensor between two flat objects for a few days. Any bending of the sensor may result in a non-zero at-rest value. Store sensor in flat position for best results.
  4. Using adhesive to attach the sensor may result in a non-zero value when no force is applied
