TLDR
This paper explores the possibility of harnessing the energy expended during the user's everyday actions to generate power for his or her computer, thus eliminating the impediment of batteries.Abstract:
Batteries add size, weight, and inconvenience to present-day mobile computers. This paper explores the possibility of harnessing the energy expended during the user's everyday actions to generate power for his or her computer, thus eliminating the impediment of batteries. An analysis of power generation through leg motion is presented in depth, and a survey of other methods such as generation by breath or blood pressure, body heat, and finger and limb motion is also presented.read more

Energy harvesting vibration sources for microsystems applications
TL;DR: A comprehensive review of existing piezoelectric generators is presented in this paper, including impact coupled, resonant and human-based devices, including large scale discrete devices and wafer-scale integrated versions.
Journal ArticleDOI
A study of low level vibrations as a power source for wireless sensor nodes
TL;DR: The goal of this paper is not to suggest that the conversion of vibrations is the best or most versatile method to scavenge ambient power, but to study its potential as a viable power source for applications where vibrations are present.

Mechanical work in terrestrial locomotion: two basic mechanisms for minimizing energy expenditure
TL;DR: During running, trotting, hopping, and galloping, the power per unit weight required to maintain the forward speed of the center of mass is almost the same in all the species studied and the sum of these two powers is almost a linear function of speed.

The sources of external work in level walking and running.
TL;DR: A simple model, assuming that in walking the body rotates as an inverted pendulum over the foot in contact with the ground, fits the experimental data better at intermediate speeds but is no longer tenable above 7 km/hr.
