Exploiting Benefits of a Periodically-Forced Nonlinear Oscillator for Energy Harvesting from Ambient Vibrations

Energy Harvesting from Train Vibrations

An investigation is carried out into how much energy can be harvested from the vibration of a passing train using a mechanical oscillator. The harvested energy could be used, for example, to charge sensors mounted on the railway track for structural health monitoring. The dominant frequencies due to a passing train are determined for a specific train and speed from a recorded acceleration time-...

Forced Vibrations for a Nonlinear Wave Equation

Harvesting Energy from Moth Vibrations during Flight

This paper presents the design, fabrication, and testing of a harvester that extracts energy from moth-body vibrations during flight. The target moth is manduca sexta, which has a payload capacity near 1 g, and a dorsal payload volume approximately 8 mm wide and 15 mm tall. Operating within these constraints, the energy harvester is designed to deliver 1 mW of electrical power at 1 VDC for gene...

Vibration Energy Harvesting: Linear and Nonlinear Oscillator Approaches

An important question that must be addressed by any energy harvesting technology is related to the type of energy available (Paradiso et al., 2005; Roundy et al., 2003). Among the renewable energy sources, kinetic energy is undoubtedly the most widely studied for applications to the micro-energy generation1. Kinetic energy harvesting requires a transduction mechanism to generate electrical ener...

Piezoelectric energy harvesting from heartbeat vibrations for leadless pacemakers

This paper studies energy harvesting from heartbeat vibrations using fan-folded piezoelectric beams. The generated energy from the heartbeat can be used to power a leadless pacemaker. In order to utilize the available 3 dimensional space to the energy harvester, we chose the fan-folded design. The proposed device consists of several piezoelectric beams stacked on top of each other. The size for...
