Advanced Materials Technologies, EarlyView.Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Could cell membranes produce acoustic streaming? Making the case for synechococcus self-propulsion [PDF]
, 2009 Sir James Lighthill proposed in 1992 that acoustic streaming occurs in the inner ear, as part of the cochlear amplifier mechanism. Here we hypothesize that some of the most ancient organisms use acoustic streaming not only for self-propulsion but also to

, 1965 Abstract Acoustic streaming is steady fluid flow produced by conservation of momentum associated with the absorption of sound. The basic equations are obtained by time-averaging the momentum equation with shear and bulk viscosity included. A volume integral for streaming in a free field produced by an arbitrary sound field is used to obtain a
