Abstract: A microstructured device is disclosed utilizing Coulomb field modification of surface energy and electroadhesion to localize a device surface or to levitate a device surface with respect to a target surface. The surface energy modification can be permanent or reversible depending on whether the charge is externally delivered to the device or derived on the device galvanically. The microstructure aspect of the device induces various hydrophilic/hydrophobic interactions with the target surface. The Coulomb field can be used to enhance or decrease the hydrophilic/hydrophobic interactions. In combination, the disclosed electro-microstructured device provides for localizing implants in a mammalian body, and additionally means for controlling cell interaction with the implant.

Abstract: A power tool that includes a housing, a motor, an end effector, an electrostatic clutch assembly, and a control circuit is provided. In a first mode of operation, the control circuit causes a first voltage to be applied to a first electrode and a different second voltage to be applied to a second electrode, generating a first attractive force between the first and second electrodes, which causes an output member to rotate together with an input member when a torque on the output member is less than or equal to a first threshold value and which causes the output member to rotationally slip relative to the input member when the torque on the output member exceeds the first threshold value, interrupting torque transmission from the input member to the output member.

Abstract: At least some embodiments of the present disclosure direct to an electrostatic sheet jamming device formed by a sheet having a conductive layer and a dielectric layer. The jamming device includes a first section of the sheet, the first section being separated from the sheet, and a second section of the sheet, the second section being separated from the sheet. The sheet is non-extensible and flexible. The first section and the second section are slidable relative to each other in a first state. The first section and the second section are jammed with each other in a second state when a voltage is applied between a conductive layer of the first section and a conductive layer of the second section.

Abstract: Disclosed embodiments include electroadhesion devices for securing smartphones and other consumer devices to target surfaces. In various embodiments, the electroadhesion device may include a digital switch for adjusting the output voltage generated by a voltage converter. The digital switch may enable safe operation of the electroadhesion device by ensuring the output voltage generated by the voltage converter is compatible with the target surface. To determine a compatible output voltage, the electroadhesion device may include one or more sensors that may measure one or more characteristics of the target surface including conductivity, porosity, hardness, smoothness, and the like.
