Abstract: Recently, there has been an increased demand for power harvesting as a source of providing \nrenewable energy. One of the most promising technologies due to their high power densities are \npiezoelectric devices, harvesting vibrational energy. There has been extensive research done in the \narea of energy harvesting using smart materials. However, the majority of this work is dedicated to \nthe application of one type of smart material, such as piezoelectric or shape memory alloy. The aim of \nthis paper is to develop a completely novel concept of a hybrid device combining piezoelectric and \nshape-memory alloy effects. The resulting device has a strong potential for miniaturisation and \npractical biomedical applications in environments characterised by thermal fluctuations. Both finite \nelement and analytical models were developed to describe the dynamic behaviour of this innovative \ndevice. Both models predicted parametric behaviour for an input frequency of 988 Hz. Performance \nof the device was comparable to existing energy harvesting devices. The limitations and benefits of \neach modelling approach are also discussed. \n
