A small, round touch sensor. Contact pressure provides continuous control. Recommended for forces from 1 N (0.1 Kg, 0.2 lb) all the way upto 98 N (10 Kg, 22 lb). Active area is a 13 mm (0.51 inch) diameter disk. If you are just looking for a button check the TouchMiniOn.
And look it's part of a family. Here are it's relatives (note that some of these sensors have a different response curve):
Application examples
- Use as a touch sensor for a synthesizer.
- Can be easily worn or applied to a variety of flat surfaces.
Blow Laurie Anderson, Marillion and others away. Trigger those samples!
- May be used to design your own fretless base. Use for capturing slaps while the
SlideLong functions
as your pitch controller.
A GForce2D-2
will help you accentuate your tones when you move the stem upright.
- Can be used in your custom wind instrument design. Use for buttons, while using a
Slide for octave control and
a GForce3D-3 to capture body movements.
- Create a fancy control panel by combining with
SlideWide,
SlideLong,
Push2D,
TouchMiniOn and
Reach sensors, to name a few.
