If you have ever rubbed a clean, wet finger on the edge of a wine glass, you may have heard the wine glasses make a singing sound. As your finger moves along the rim of the glass, it sticks and slides ...

A new method uses condenser microphones and neural networks to estimate droplet radius from resonant frequency.

We propose a sub-1 Hz resonance frequency MEMS resonator that can be used for seismometers. The low resonance frequency is achieved by an electrically tunable spring with an ultra-small spring ...
