Over the last decade the energy harvesting technology has been very intensively developed for self-powered mobile electronics. One of the most promising are systems that convert human-body motion to electricity. This was made possible due to reducing the power consumption of modern wearable electronic devices. There exist many of motion energy-harvesting techniques based on various physical principles: piezoelectric, triboelectric, electromagnetic, and electrostatic and others. However, unfortunately, the direction of mechanical movement, which can be harvested by a triboelectric [1] or piezoelectric [2] energy generator, is usually limited to a single direction. Therefore, the development of devices that do not depend on the direction of movement is very popular in the market [3]. In addition, due to small efficiency of each of transformation principles, many systems work simultaneously using multiple conversion methods. The massive development of the world electronic technology follows a general trend of miniaturization, portability and functionality. The development of mobile phones is a typical example of miniaturization, from the transistors based on huge-size machines, to solid state MOSFET based on handhold cell phones or smart watches with communication functionality. Such small size electronic devices operate at ultralow power consumption, making it possible to be powered by the energy harvested from our living environment [1]. New technologies that can harvest energy from the environment as sustainable self-sufficient micro-power sources are a newly emerging field of nanoenergy, which is connected with applications of nanomaterials and nanotechnology for harvesting energy to power micro or nano-systems. We have mainly utilized two physical effects for harvesting small-magnitude mechanical energies: piezoelectric and triboelectric ones. The first of these is described quite well in the literature [2], so the seco[...]
