Description
Keju Ji and co-authors etch in a 2026 paper large metal molds for mushroom tipped bionic adhesives. Such tips spread stress and grip better than flat posts on sticky pads. Mold making for these shapes has been costly, fussy, and hard to scale.
Their route etches both faces of a plate in turn, carving mushroom forms in tens of minutes. Etch time and mask size tune neck spot and taper angle with repeatable control. Cast copies grip at up to 17.37 newtons per square centimeter in room air. Grip holds at 98.26% of that level in vacuum in their tests. The pads also shrug off micro vibration and fit rough surfaces well.
