[James Eckert] got his hands on a Freescale MPR121 capacitive touch sensor. The chip in question speaks I2C and senses up to twelve simultaneous capacitive sense electrodes; break-out boards are ...

Capacitive sensing ... parts to replicate a whole lot of touch interfaces – buttons can easily be made into a smallish keyboard, and the radial touch sensor will emulate the ‘wheel ...

Using multi-material 3D printing and computational tools, this work demonstrates an approach to generate and fabricate conductive traces within objects to support capacitive touch sensing. Touching ...

The sensors in most current systems rely on direct touch causing a physical deformation of a contact layer, leading to changes in electrical capacitance ... control over the structure and pattern ...
