摘要： An energy harvesting apparatus and method that is especially well suited for harvesting low frequency broadband vibration energy from a vibrating structure is presented. The apparatus includes a pair of disc springs that are arranged in an opposing relationship. A threaded fastening member and a threaded nut extend through apertures in each of the disc springs and enable a predetermined preload force to be applied to the disc springs. The preload effectively “softens” the disc springs, thus heightening the sensitivity of the disc springs to low frequency, low amplitude vibration energy. A piezoelectric material ring is secured to each of the disc springs. Each piezoelectric material ring experiences changes in strain as its associated disc spring deflects in response to vibration energy experienced from a vibrating structure. The electrical output from each piezoelectric material ring can be used to power or activate various forms of electronic sensors and devices, or it can be conditioned and stored in a circuit for later use.

摘要： A self-powered sensor system and sensing method includes a power source generating power which is a function of a first parameter such as vibration. A charge management circuit is responsive to the power output by the power source and is configured to provide, every charge cycle, a supply signal to a controller which activates it to control a transmitter to transmit data at a transmission rate which is a function of the charge cycle. The data and the transmission rate are processed and used to identify a variation in the first parameter by a variation in the transmission rate beyond a predetermined threshold.

摘要： Embodiments of a vibrational energy harvester are provided. A vibrational energy harvester can include a translator layer sandwiched between two stator layers. The translator layer can include a plate having an array of magnets and two or more piezoelectric patches coupled to a tether beam attached to the plate. The stator layers can have a printed circuit board with multilayer electrical windings situated in a housing. In operation, vibration of the housing can result in bending of the piezoelectric patches coupled to the tether beam. This bending simultaneously results in a relative displacement of the translator, which causes a voltage potential in the piezoelectric patches, and a relative velocity between the translator and the stators, which induces a voltage potential in the stator coils. These voltage potentials generate an AC power, which can be converted to DC power through a rectification circuit incorporating passive and active conversion.

摘要： A vibration-based power generator has a variable stiffness oscillator connected to a base. The oscillator comprises an inertial mass moving relative to the base in response to vibrations. The oscillator has a neutral position corresponding to a position of the oscillator when no vibrations are transmitted to the base. The oscillator has a first position where the mass is at a first distance and a second position where the inertial mass is at a second distance from a position of the mass when the oscillator is in neutral position. The second distance is greater than the first distance. A stiffness of the oscillator at the second position is greater than a stiffness of the oscillator at the first position. A transducer generating electric power in response to movement of the inertial mass is associated with the oscillator. A method of optimizing a vibration-based power generator is also presented.
