Dual-frequency resonance tracking (DFRT) is a technique that utilizes contact mode atomic force microscopy (AFM) to measure a sample’s weak electrical or mechanical responses. Conventional resonance ...

As a musician and sacred sound and light artist, Blanche has spent decades working with tone, harmonic entrainment, and the physiological effects of sound. His practice spans tuning forks applied ...

Mechanical resonance is a pervasive problem in servosystems. Most resonance problems are caused by compliance of powertransmission components. Standard servocontrol laws are structured for rigidly ...

Harmonic distortion is not a problem unless it becomes a problem. Harmonics are a breakdown of a distorted waveform into its separate frequencies, which are integer multiples of the fundamental ...

Download this article in PDF format. Jacques and Pierre Curie, French physics, discovered the piezoelectric effect in 1880. When some solid material is mechanically compressed or stressed, the ...

Quantitative characterization of nanomechanical properties has invariably been a holy grail for atomic force microscopy. This article explains some of the industry’s earlier attempts made at ...
