This review highlights various modes of converting ambient sources of energy into electricity
using soft and stretchable materials. These mechanical properties are useful for emerging …

Fluid bridges are ubiquitous soft structures of finite size that conform to and link the surfaces
of neighboring objects. Fluid joints, the specific type of fluid bridge with at least one extremity …

Contact-angle hysteresis of a liquid suspended on surface microstructures, namely in a
Cassie–Baxter state, is determined mainly by the receding contact line although not fully …

Asymmetric mechanical transducers have important applications in energy harvesting,
signal transmission, and micro-mechanics. To achieve asymmetric transformation of …

Nonlinear elastic materials are significant for engineering and micromechanics. Droplets
with the merits of easy‐accessibility, diversity, and energy‐absorption capability exhibit a …

This paper presents the rotation control design and experimental performance of a
microelectromechanical systems (MEMS) variable-capacitance motor where a free-spinning …

A thrust bearing consisting of an air cushion formed within a liquid ring has been developed,
which takes advantage of the Laplace pressure induced by the liquid/air surface tension. As …

Liquid menisci at millimeter length scales and smaller exhibit large Laplace pressures. To
utilise these effects, liquid ring bearings have recently been developed, which consist of …

This study develops a ferrofluid-lubricated thrust bearing with an air cushion. The bearing
comprises a rotor, a stator, and a ferrofluid ring formed between them due to absorption by …

In this paper, the supporting capacity of a ferrofluids (FFs) ring bearing is investigated
experimentally and numerically. The bearing consists of a floating plate, a substrate, and a …
