Force anisotropy in resonant acoustic levitators [PDF]
The Journal of the Acoustical Society of America, 1989 In general, the forces positioning a sample in an acoustic levitator depend on direction, which is to say they are anisotropic. The anisotropy of the acoustic force for several classes of levitating modes in rectangular and cylindrical resonators has been investigated.

Yoctonewton force detection based on optically levitated oscillator
Fundamental Research, 2023 Optically levitated oscillators in high vacuum have excellent environmental isolation and low mass compared with conventional solid-state sensors, which makes them suitable for ultrasensitive force detection. The force resolution usually scales with the measurement bandwidth, which represents the ultimate detection capability of the system under ideal ...
