I-CubeX Online Store - TouchMicro v1.0 : Contact pressure sensor

TouchMicro-5 v1.0 (obsolete)

The micro, round version of the Touch sensor. Contact pressure provides continuous control. Senses from 1 N (0.1 Kg, 0.2 lb) all the way upto 98 N (10 Kg, 22 lb) on a 5 mm (0.2 inch) diameter disk. Here are it's other relatives: TouchMini, TouchStrip and TouchGlove. See this videoclip for a demo !

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 touch sensor for synthesizer
May be used to design your own fretless base. Use for capturing slaps while the SlideLong functions as your pitch controller. A GForce2D&Tilt2D 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 GForce2D&Tilt2D to capture body movements.
Create a fancy control panel by combining with SlideWide, SlideLong, Push2D, TouchMiniOn and Reach sensors, to name a few.
