Patent attributes
An electronic device such as a fabric item or other item may have control circuitry. Buttons such as fabric-based buttons may be mounted within the device. A user may depress the buttons when it is desired to control operation of the device. Each button may have sensor circuitry such as capacitive sensor circuitry or resistive sensor circuitry. A control circuit can monitor conductive structures in the button to detect changes in electrical button characteristics such as capacitance and resistance and thereby gather information on button press events. Fabric buttons may have fabric movable button structures that are coupled to fabric support structures by fabric biasing structures. The fabric biasing structures may contain strands of material that are configured to form bistable fabric springs and/or hinges. The biasing structures and other fabric structures in a fabric button may be formed from knit fabric or other intertwined strands of material.
