AB  - Conversion of ambient energy to usable electrical energy is attracting attention 
      from researchers since providing a maintenance-free power source for the sensors 
      is critical in any IoT (Internet of Things)-based system and in SHM (structural 
      health monitoring). Continuous health monitoring of structures is advantageous 
      since the damage can be identified at inception and the necessary action taken. 
      Sensor technology has advanced significantly, and MEMS (microelectromechanical 
      systems)-based low-power sensors are available for incorporating into large 
      structures. Relevant signal conditioning and transmission modules have also 
      evolved, making them power-efficient and miniaturized. Various micro wireless 
      sensor nodes (WSN) have also been developed in recent years that require very 
      little power. This paper describes the applications of a novel tunable 
      piezoelectric vibration energy harvester (PVEH) for providing autonomous power to 
      low-power MEMS sensors for use in IoT and remote SHM. The novel device uses 
      piezoelectric material and an ionic polymer-metal composite (IPMC) and enables 
      electrical tuning of the resonant frequency using a small portion of the power 
      generated.
