Abstract
Electrostatic dry adhesive devices having a microstructured dry adhesive element formed directly into a contact surface of an electrostatic adhesive. The microstructured dry adhesive element, such as in the form of microwedges, can be molded into surface of an electrostatic adhesive. Also provided are associated methods of making such adhesive devices.
Claims21
An adhesive device comprising:
- a microstructured dry adhesive element formed directly into a contact surface of an electrostatic adhesive.
An adhesive device comprising:
- a dry adhesive element having microwedges molded into a contact surface of an electrostatic adhesive comprising at least one conductive electrode embedded in a moldable polymer.
A method of making an electrostatic dry adhesive, the method comprising:
- coating a moldable polymer onto a mold of a dry adhesive,
- applying a second layer of the moldable polymer onto the moldable polymer coating and embedding electrodes in the second layer of the moldable polymer,
- applying a third layer of the moldable polymer on top of the second layer to completely encapsulate the conductive mesh to form an electrostatic dry adhesive precursor and
- finally curing the curing the electrostatic dry adhesive precursor to create the electrostatic dry adhesive.
