Vibration sensing is important for sensing failure of instrumentation or found sound and vibration measurements. Technology for detecting sound has existed for a long time and usually employs a variety of microphones. However, vibration is difficult to measure easily. There have been many reports of utilization of microelectromechanical systems (MEMS) based technology such as this…

A recent paper in Nature has created a zero…
Device companies often try to fulfill a need in the market. For example if the need in the market is irregular heartbeat then the companies are tempted to create pacemakers in collaboration with doctors which enable them to create devices that would regulate that heartbeat electronically.
