摘要： An electronic device for processing impedance changes is provided. The electronic device receives, from a wearable device that includes (i) a first biopotential-signal sensor configured to contact a first sensor-skin interface when the wearable device is worn on a body part of a user, and (ii) a second biopotential-signal sensor configured to contact a second sensor-skin interface when the wearable device is worn on the body part of the user, data indicating impedance values at the first and second sensor-skin interfaces. The method further includes, after physical contact by an object other than the body part with or near the body part of the user, based on obtaining (i) a first impedance change at the first sensor-skin interface and (ii) a second impedance change at the second sensor-skin interface, determining whether the physical contact corresponds to a user command to control the wearable device or another electronic device.

摘要： Disclosed apparatus may include a membrane, a first electrode supported by the membrane, a second electrode, and optionally a controller configured to control an electrical potential applied between the first electrode and the second electrode. Example apparatus may include one or more flexible membranes that may, at least in part, define an enclosure that is at least partially filled with a dielectric fluid. A flexible membrane may include a functionalized polymer or inorganic dielectric material, such as a fluoropolymer composite including at least one electrically conductive additive and/or at least one toughener. Examples also include associated materials (e.g., polymers), methods of fabrication, methods of apparatus operation, and systems.
