  • Systems and methods for touch sensing based on resistor-capacitor delays
    Patent number: 12737067
    Abstract: An exemplary system and method for a single-conductor capacitive touch or contact sensor or human-machine-interface that can be integrated into a 2D or 3D-formed body. The exemplary system and method can be employed in the design and/or construction/fabrication of a tactile sensor-device having minimal instrumentation and wiring to provide interactive functionality. In some embodiments, the exemplary system and method can provide n number of sensing nodes on a device through the use of a single channel input of a controller without multiplexing by evaluating and encoding each sensing node to an RC delay uniquely established for the sensing node.
