Non-ideal excitation approach for piezoelectric vibration based energy harvesting
(2014-01-01)
Common solution for energy harvester device is project design according harmonic excitation around natural frequency matching excitation source. Environment vibration is random and wide band causing short time of resonance ...
Harvesting Energy from fat-tail random vibrations
(ASAMACI, 2015-04)
We illustrate how applied and computational mathematics tools in the field of probability, statistics and stochastic processes are applied in the preliminary design stage of an expectedly typical 21th century (nanotech) ...
An investigation into the simultaneous use of a resonator as an energy harvester and a vibration absorber
(Elsevier B.V., 2014-02-28)
A mass-spring-damper system is at the core of both a vibration absorber and a harvester of energy from ambient vibrations. If such a device is attached to a structure that has a high impedance, then it will have very little ...
Respostas neuromusculares agudas a estimulação vibratória local no exercício de flexão de cotovelo em banco scott
(Universidade Federal de Minas GeraisUFMG, 2013-04-26)
The deleterious effects on health-related vibration in the field of physical medicine and occupational therapy have been previously reported. In sports these rules arent existents, although in several sports athletes undergo ...
High-Frequency, Low-Intensity Vibrations Increase Bone Mass and Muscle Strength in Upper Limbs, Improving Autonomy in Disabled Children
(WILEY, 2011)
Disuse osteoporosis in children is a progressive disease that can affect quality of life. High-frequency, low-magnitude vibration (HFLMV) acts as an anabolic signal for bone and muscle. We undertook a prospective, randomized, ...
