An energy harvester includes an elongated tubular casing extending around a longitudinal axis between opposed first and second ends. A body is arranged in the casing. A helical electrical winding is wound around the longitudinal axis. The body is arranged to move along the longitudinal axis with alternate motion away from the first end towards the second end and away from the second end towards the first end. As a result of this alternate motion, an electromotive force is produced in the at least one helical electrical winding. Furthermore, at least one of the first and second ends includes a piezoelectric transducer that is configured to co-operate in a kinetic energy transfer relationship with the at least one body to generate an electric voltage as a result of the at least one body reaching, in the alternate motion, an end-of-travel position towards the piezoelectric transducer.

Energy harvester and corresponding device

A nonlinear dynamic system comprising: a number N of nonlinear components, wherein each nonlinear component experiences intrinsic oscillation when a coupling parameter &#x3bb; is tuned past a threshold value, and wherein the nonlinear components are unidirectionally coupled together in a ring configuration; and a signal generator configured to generate N coherent locking signals; wherein each locking signal is phase shifted by 2&#x3c0;/N with respect to the other locking signals; and wherein the signal generator is coupled to the nonlinear components such that each locking signal locks a frequency of the intrinsic oscillation of one of the nonlinear components to a frequency of the locking signal.
