“…With the development of the portable electronics and wireless sensors, energy harvesting is becoming a very attractive technique for a wide variety of self-powered micro-electro-mechanical systems (MEMS). In order to satisfy the self-powering demands of micro-power electronics in different fields, the scholars have successfully developed various kinds of piezoelectric energy generators and the vibration generators [1,2] and the rotary generators [3,4]. At present, domestic and foreign research institute research micro-generator about wind energy transformed into electrical energy is still relatively little.…”

To achieve a fluid energy recovery by piezoelectric generator, a piezoelectric wind energy harvester (PWEH) is presented and investigated experimentally. Making use of the force generated by the flow of wind to vibrate the piezoelectric material, the mechanical energy harvested from the vibration of the piezoelectric material is converted into electrical energy. The testing results show that when the end of piezoelectric vibrator isn't added a proof mass and the wind speed is constant, the maximum peak voltage appears between the excited angle of 30° to 45°. When the excited angle is greater than 45°, the voltage is gradually decreases as the excited angle increases. In the case of constant angle, the generated voltage rises with the wind speed increased within a certain range. Adding a proof mass at the end of the piezoelectric vibrator makes voltage produced by the PWEH increase observably. When wind speed, excited angle and the weight of proof mass meet a appropriate matching, the excited frequency of piezoelectric vibrator and natural frequency is equal, the PWEH achieves resonance condition, and the generating performance of the PWEH is optimum.

In the last few years, there has been intensive research in the field of human motion and environment energy harvesting. That kind of energy harvesting used for power supply self-regulation in eWALL system (e WALL for Active Long Living) would contribute to increased energy efficiency of the system. The paper will represent possible methods and ways of energy harvesting in eWALL system. Statistical evaluation of the harvested energy will be given. The paper will also consider other, possible undeveloped ways of energy harvesting in terms of the practical implementation of the system. These methods and statistical estimates may relate to eWALL system, but also to other systems such as e.g. smart homes. Energy accumulation can be achieved from user motion, differences in ambient temperature, vibrations, radio frequency radiation and other technologies that are available to eWALL users.I.
