Kempen, Sander (author)This paper presents a manufacturing method for a zero-stiffness compliant mechanism to be used as a flexible head support. The manufactured design consists of two curved, thin-walled U-beams made of high strength steel. The beams are prestressed in opposite directions to obtain zero torsional stiffness so that rotation of the head is allowed....master thesis 2021

van de Wetering, E. (author), Blad, Thijs (author), van Ostayen, R.A.J. (author)In this work, a stiffness compensated piezoelectric vibration energy harvester is modelled and tested for low-frequency excitations and large input amplitudes. Attracting magnets are used to introduce a negative stiffness that counteracts the stiffness of the piezoelectric beam. This results into a nearly statically balanced condition and...journal article 2021
