The area of micro power generation has developed significantly over the last two decades in
the field of microelectromechanical systems, self-powered wireless sensor nodes, and …

In this paper, we proposed and experimentally validated a vibration-based multimodal
hybrid piezoelectric–electromagnetic energy harvester having multiple mechanical degrees …

Powering electronics without depending on batteries is an open research field. Mechanical
vibrations prove to be a reliable energy source, but low-frequency broadband vibrations …

Among the main vibration-to-electricity conversion systems, resonant harvesters suffer from
a series of strong limits like their narrow frequency response and poor output power at small …

The abundant mechanical energy distributed in ambient environments features ultra-low
frequency. Implementation of self-sustained low-power electronic systems is largely …

Small-scale electronic devices need self-powering technology, and one way to do that is to
use mechanical energy harvesters. These devices can turn ambient mechanical energy into …

Tribotronics is an emerging research field that focuses on the coupling of triboelectricity and
semiconductors. In this review, we summarise and explore three branches of tribotronics …

Electromagnetic vibration transducers are seen as an effective way of harvesting ambient
energy for the supply of sensor monitoring systems. Different electromagnetic coupling …

These days the health monitoring of machines and structures is performed using wireless
sensor nodes (WSNs). The disadvantage of short life span of batteries in WSN is overcome …
