A cuttable multi-touch sensor

We propose cutting as a novel paradigm for ad-hoc custom-ization of printed electronic components. As a first instanti-ation, we contribute a printed capacitive multi-touch sensor, which can be cut by the end-user to modify its size and shape. This very direct manipulation allows the end-user to easily make real-world objects and surfaces touch-interactive, to augment physical prototypes and to enhance paper craft. We contribute a set of technical principles for the design of printable circuitry that makes the sensor more robust against cuts, damages and removed areas. This in-cludes novel physical topologies and printed forward error correction. A technical evaluation compares different to-pologies and shows that the sensor remains functional when cut to a different shape
