Although vibration sensors are among the more niche things you can get for your smart home, there are some useful & creative ways to implement them.

This paper presents the modeling, fabrication, and testing of a high-performance dynamic strain sensor. Using microelectromechanical systems (MEMS) technology, ZnO piezoelectric microsensors are ...

The vibration energy available abundantly in nature by various sources can be used for energy harvesting purpose and the vibration of machines can be used for condition monitoring of the machines.
