Abstract
One example provides a wireless wearable device including a flexible wearable base configured to be worn at a location of a skeletal joint, an electrostatic clutch including a first electrode, the first electrode having two or more first electrode sheets, each first electrode sheet having a core, a conductive layer formed on the core, and a dielectric coating formed on the conductive layer, and also having a common conductor to which each of the first electrode sheets are connected, and a second electrode having two or more second electrode sheets arranged alternately with the first electrode sheets in a stacked arrangement, a tensioner coupled to the electrostatic clutch, a battery, and control circuitry coupled to the electrostatic clutch and configured to generate a control signal to control an electrostatic force between the two or more first electrode sheets and the two or more second electrode sheets.
