This book investigates several non-resonant inductive harvester
architectures in order to find the magnet coil arrangement that
generates the largest power output. The book is useful as a step-by-step
guide for readers unfamiliar with this form of energy harvesting, but
who want to build their own system models to calculate the magnet motion
and, from that, the power generation available for body-worn sensor
systems. The detailed description of system model development will
greatly facilitate experimental work with the aim of fabricating the
design with the highest predicted power output.
Based on the simulated optimal geometry, fabricated devices achieve an
average power output of up to 43 mW during walking, an amount of power
that can supply modern low-power, body-worn systems.
Experiments were also carried out in industrial applications with power
outputs up to 15 mW. In sum, researchers and engineers will find a
step-by-step introduction to inductive harvesting and its modeling
aspects for achieving optimal harvester designs in an efficient manner.
