Ferroelectrics found extensive uses in industrial applications because of their unparalleled electromechanical and electrical characteristics, for example, as actuators, sensors and capacitors [1], [2 ...

Something that probably unites many Hackaday readers is an idle pursuit of browsing AliExpress for new pieces of tech. Perhaps it’s something akin to social media doomscrolling without the induced ...

Magnetic resonance force microscopy (MRFM) is a scanning probe technique based on coupling a soft magnetic tipped cantilever to the spins of a sample, and measuring the tiny force arising from spin ...

It is known that the human body can generate mechanical vibrations at very low frequencies, so-called infrasonic waves. Such low-frequency vibrations are produced by physiological processes—heartbeats ...

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 ...

The sub-20 MHz frequency is merely the fundamental resonance, other resonances can be achieved in the same crystal at multiples of the fundamental. This effect can be readily demonstrated through ...

Mechanical resonance, one of the most perplexing problems in motion control, in inherent in most machines. It usually shows up when you're trying to tune a controller for the first time. What you'll ...

With an increase in variable frequency drives, resonance problems are becoming more common. Here's some advice on what you can do about it. In the event of a breakdown, any number of issues may be the ...

Almost anytime physicists announce that they’ve discovered a new particle, whether it’s the Higgs boson or the recently bagged double-charm tetraquark, what they’ve actually spotted is a small bump ...
