A sensor no one should do without. 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 square surface of 38 x 38 mm (1.5 x 1.5 inch). See this videoclip for a demo !
And look, it's part of a family. Here are it's relatives (note that some of these sensors have a different response curve):
- TouchMicro-3 (smoother response !)
- TouchMicro-5
- TouchMicro-10 (smoother response !)
- TouchMini
- TouchStrip
- TouchGlove.
Application examples
- Can be easily worn or applied to a variety of flat surfaces. Blow Laurie Anderson, Marillion and others away. Trigger those samples!
- Use as a touch controller, eg. for a synthesizer.
- Create a fancy control panel by combining with SlideWide, SlideLong, Push2D, TouchMiniOn and Reach sensors, to name a few.
