Wafer‐Scale Electroactive Nanoporous Silicon: Large and Fully Reversible Electrochemo‐Mechanical Actuation in Aqueous Electrolytes (Adv. Mater. 1/2022)

Abstract

Electro-Actuation In article number 2105923, Manuel Brinker and Patrick Huber report laser cantilever bending experiments that show large and reversible electrosorption-induced deformation of wafer-scale nanoporous silicon in aqueous electrolytes (isotonic saline solution) at exceptionally small operation voltages. This paves the way for on-chip integrated actuation and stress generation, e.g., in (bio-)medical environments, as is illustrated by electro-mechanical stimulation of living cells.
