Bioinspired pressure actuated adhesive system
Abstract(#br)We developed a dry synthetic adhesive system inspired by gecko feet adhesion that can switch reversibly from adhesion to non-adhesion with applied pressure as external stimulus. Micropatterned polydimethylsiloxane (PDMS) surfaces with pillars of 30\u003cce:hsp sp=\"0.25\"/\u003eμm length and 10\u003cce:hsp sp=\"0.25\"/\u003eμm diameter were fabricated using photolithography and moulding. Adhesion properties were determined with a flat probe as a function of preload.
