Abstract
Touch sensitive musical instruments are described herein including embodiments having: one-sided capacitive touch sensors with conductive ground planes, one-sided capacitive touch sensors with air gaps, one-sided capacitive touch sensors with separating material, and/or one-sided capacitive touch sensors including a combination of conductive ground planes, air gaps, and/or separating material. Embodiments of touch sensitive musical instruments simulating string instruments such as guitars are described.
Claims10
A touch sensitive musical instrument comprising:
- a capacitive touch sensor layer comprising conductive ink printed on a thin film substrate, further comprising a capacitive element with a conductive ink grid having less than complete conductive ink coverage, wherein a user touching or coming close to the capacitive touch sensor layer changes the capacitive element's effective capacitance by combining the person's capacitance with the capacitance of the capacitive element;
- a separation layer adjacent the capacitive touch sensor layer;
- and
- a conductive ground plane layer adjacent the separation layer configured to shield a backside of the capacitive touch sensor layer.
