摘要： Currently, the personal portable electronics are powered by traditional batteries. However, as the electronic elements and power consumption increase, the power source has become an issue because it is impractical to frequently recharge or replace the batteries. Especially, for implanted and biomedical electronic systems, to replace the power sources is unrealistic. Moreover, list of the shortcomings of the conventional power sources includes not only the limited capacity but also environmental pollution and possible explosion and health hazards. Besides, the heavy and rigid boxy batteries hinder the further development of ?exible and wearable electronics and biomedical electronics. On the other way, most of the existing sensing technologies need to be pre-supported and pre-offered electrical or optical signals to sense environmental information, which inevitably requires foreign power sources. With the increased number and density of sensing networks, the sensors that can be of low-power consumption or even self-powered will be desired for future electronic modules [1–7]. TENG was ?rst invented by Zhong Lin Wang’s group in 2012 [8]. A more and deep study and discussion about TENGs can be found in another reference book [1]. Such devices utilize the conjunction of the triboelectri?cation and electrostatic induction to convert ubiquitous mechanical energy into electricity. The devices can act as ef?cient and sustainable energy converters and providers from harvesting environment low-frequency mechanical energy, such as wind, wave, river ?ow, rain drop, human body motions, and so forth [2–6, 9]. The collected energy can be converted to electric energy sources for continuously powering electronic devices and even systems [10]. Triboelectric effect is a contact-induced electri?cation in which a material turns into electrically charged after it is physically contacted with another different kind of materials. It is a natural phenomenon, and, probably, most of the people have been experiencing the triboelectric phenomena in our daily life. However, the mechanisms and availability of triboelectri?cation were seldom to be explored [11, 12].
