Patent number: 10224835Abstract: The invention relates to a bistable piezoelectric cantilever-based vibration energy harvester that increases the energy harvested over a broad frequency of vibrations by introducing bistability to the cantilever through use of two repelling magnets, one mounted on the cantilever and one at a location facing the first. This increases the amplitude and velocity of cantilever vibration, hence harvested power, while nonlinearity makes the system efficient over almost the entire range of frequencies, lower than the natural resonant frequency of the linear version without the magnets. Such improved performance is seen while the cantilever remains in the bistable mode.Type: GrantFiled: April 11, 2016Date of Patent: March 5, 2019Assignee: Iowa State University Research Foundation, Inc.Inventors: Kanishka Aman Singh, Ratnesh Kumar, Robert J.
