In article authors review the state and prospects of development of the modern market of piezoelectric devices; give the main design features of bimorph piezoelectric elements; present results of the analysis of modern technical literature and patent documentation. Results of research of patent activity on bimorph piezoelements for five leading countries in this area (the USA, Japan, Germany, France, Russia) are presented. The purpose of work is to carry out a research review of patent activity in the field of piezoelectric devices and identification of the generalized methods of their capacity improvement. Authors have developed the classification of constructive methods of improvement for three main operational characteristics of bimorph elements - sensitivity, mechanical durability and range of output size. Analysis allowed to clear common receptions for improving of a set of operational characteristics at the same time.
