The Casimir force is the attraction between uncharged metallic surfaces as a result of quantum mechanical vacuum fluctuations of the electromagnetic field. We demonstrate the Casimir effect in microelectromechanical systems using a micromachined torsional device. Attraction between a polysilicon plate and a spherical metallic surface results in a torque that rotates the plate about two thin torsional rods. The dependence of the rotation angle on the separation between the surfaces is in… 
The Role of Quantum Vacuum Forces in Microelectromechanical Systems
The presence of boundary surfaces in the vacuum alters the ground state of the quantized electromagnetic field and can lead to the appearance of vacuum forces. In the last decade, landmark
Casimir forces on a silicon micromechanical chip.
TLDR
A high degree of parallelism between the two near-planar interacting surfaces can be achieved because they are defined in a single lithographic step and this scheme opens the possibility of tailoring the Casimir force using lithographically defined components of non-conventional shapes.
The Casimir effect in the nanoworld
Abstract. The Casimir effect is a force arising in the macroscopic world as a result of radiation pressure of vacuum fluctuations. It thus plays a key role in the emerging domain of
Geometry-dependent Casimir forces on a silicon chip
Quantum fluctuations give rise to van der Waals and Casimir forces that dominate the interaction between electrically neutral objects at sub-micron separations. Under the trend of miniaturization,
Strong Casimir force reduction through metallic surface nanostructuring
TLDR
It is experimentally demonstrated that by nanostructuring one of the interacting metal surfaces at scales below the plasma wavelength, an unexpected regime in the Casimir force can be observed.

Quantum fluctuations of the electromagnetic field give rise to a zero-point energy that persists even in the absence of electromagnetic sources. One striking consequence of the zero-point energy is

It is shown by means of the optical medium analogy that the static Casimir force between two conducting plates is modulated by gravitational waves. The magnitude of the resulting force changes within

TLDR
The benefits of using micro-mechanical sensors to detect the Casimir interaction are described, the most recent experimental results are summarized and potential optomechanical experiments that would allow measuring this force in regimes that are currently unreachable are suggested.
