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...
Nanoporosity in silicon results in interface‐dominated mechanics, fluidics, and photonics that are often superior to the ones of the bulk material. However, their active control, for example, by electronic stimuli, is challenging due to the absence of intrinsic piezoelectricity in the base material. Here, for large‐scale nanoporous silicon cantilevers wetted by aqueous electrolytes, electrosorption‐induced...
