We have used an atomic force microscope to make precision measurements of the Casimir force between a metallized sphere of diameter 196 \ensuremath{\mu}m and flat plate. The force was measured for plate-sphere surface separations from 0.1 to 0.9 \ensuremath{\mu}m. The experimental results are consistent with present theoretical calculations including the finite conductivity, roughness, and temperature corrections. The root mean square average deviation of 1.6 pN between theory and experiment…

TLDR
The authors' experimental results are consistent with Lifshitz's theory using the proximity force approximation (PFA), and corrections to the PFA are bounded using nine sphere-sphere and three sphere-plate measurements with spheres of varying radii.
Tests of new physics from precise measurements of the Casimir pressure between two gold-coated plates
A micromechanical torsion oscillator has been used to strengthen the limits on new Yukawa forces by determining the Casimir pressure between two gold-coated plates. By significantly reducing the
Precision measurements of the material and boundary geometry dependence of the Casimir force
The Casimir force results from the modification of the electromagnetic zero point energy which pervades all of space as predicted by quantum field theory. It depends on the conductivity, dielectric
Casimir Force in Micro and Nano Electro Mechanical Systems
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.
Casimir force between metallic mirrors
We study the influence of finite conductivity of metals on the Casimir effect. We put the emphasis on explicit theoretical evaluations which can help comparing experimental results with theory. The
Mechanical Stability and Sticking in a Model Microelectromechanical Systems (MEMS) under Casimir Forces–Part I: Corrections to the Casimir Force

Quantum Mechanical Actuation of Microelectromechanical Systems by the Casimir Force
TLDR
This work demonstrates the Casimir effect in microelectromechanical systems using a micromachined torsional device and shows that quantum electrodynamical effects play a significant role when the separation between components is in the nanometer range.
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.
