Electro-dry adhesion

摘要

The present invention will provide adhesive technology adapted to adhere indefinitely to a surface without leaving a residue or sticky mess after removal. The self-preloading force provided by the electrostatic adhesion enables the present invention to be used in applications where directly applying a preload is not possible. Furthermore, the combination of electrostatic forces and Van der Waals forces allows electro-dry-adhesives to adhere to surfaces where traditional dry adhesives and electrostatic devices fail.

主权项

1. An apparatus for electro-dry adhesion comprising:
a deformable substrate, said deformable substrate further comprising a composite polymer, rubber, or silicon rubber material with embedded conductive particles, wherein said conductive particles provide conductivity to said deformable substrate; a micro-featured surface configured to provide dry adhesion; and at least one conductive material configured to provide electrostatic adhesion and at least one non-conductive region configured to isolate said conductive material, further comprising a voltage applied to said at least one conductive material providing an attractive force to self-preload said micro-featured surface, a resistive force to self-peel said micro-featured surface, or alternating said voltage to self-clean said micro-featured surface.
