This work concerns the steady-state dynamics of eccentric-rotor harvesters under the excitation of a forced pendulum, selected as a simplified representation of the swinging motion of the human arm during locomotion, to better understand their use fo

A tremendous amount of research has been performed on the design and analysis of vibration energy harvester architectures with the goal of optimizing power output. Often, little attention is given to the actual characteristics of common vibrations fr

This paper reports modeling and analysis of a wearable rotational energy harvester from human-body motion. Our analysis started with the collection of inertial measurement unit (IMU) data from different human-body locations (wrist, chest, waist, and

The growing prevalence and variety of wearable devices has led to a renewed interest in harvesting energy from the motion of the human body. We have been working on inertial energy harvesters in which the human body motion excites a proof mass whose

We present fabrication and characterization of a wrist-worn rotational energy harvester using plucked piezoelectric unimorph beams for wearable applications. It consists of an eccentric rotor containing multiple magnets (at certain angular distance)

We present an electromagnetic energy harvester using rotational eccentric mass structure that generates power from extremely low-frequency motion of a driven mechanical swing-arm (i.e. pendulum) that is intended to mimic wrist motion during regular w

This paper presents an energy harvester based on an improved eccentric rotor to generate electrical power from human body motion. An eccentric mass is suspended by a rotational spring to enhance the mechanical energy captured from low and random freq
