SEVERAL methods for studying surface vibration modes using holography have recently been developed 1–3. These effectively contour the surface with interference fringes, which delineate points of equal ...

Patterns of vibration on the skin of the hand that are part of how we sense the world through touch have been cataloged, for the first time, by researchers. Type an email on your computer. Raise a ...

The World Health Organization reports that 360 million people worldwide are affected by hearing loss, generally caused by disease, accidents or damage to middle-ear structures. Researchers at ...

3D non-contact surface analysis is used extensively across the industry to measure surface irregularities and small displacements – it provides accurate, traceable and repeatable measurements. When ...

Today, a growing number of micro-manufactured actuators, sensors, and components vibrate at frequencies in the high MHz range. Some examples of such high-frequency vibrating systems are ...

Diverging and converging patterns forming on the surface of solidifying liquid metals resemble plotlines in a complex historical novel, in a new international study. The cyclic patterns observed are ...
