“…Representative energy management circuits include rectifier circuits [ 12 ], oscillator circuits [ 13 ], and charge pumps [ 14 ]. Improving the energy transfer efficiency in the TENG would allow it to be serve broad applications, and extensive research is underway into such energy management circuits [ 15 – 17 ]. Using energy management circuits in TENGs, such as half-wave rectifiers, full-wave rectifiers, and charge pumps, allows energy to be stored in either charge enhancement mode or voltage enhancement mode [ 18 ].…”

We investigated the polarity dependence of a capacitive energy management circuit in a triboelectric nanogenerator (TENG) power system. In a half-wave rectifying circuit, the Simulation Program with Integrated Circuit Emphasis and analytical models show that the charge dump to the load varied depending on the polarity of the rectifying circuit even with the same charge output from TENG. Depending on the polarity of the rectifying circuit, a fast saturation of the direct current (DC) output voltage or a high DC output voltage was obtained. Experiments with a half-wave rectifier and Bennet doubler confirmed our simulation and theoretical results. The charge dump from the minimum capacitance of the separated TENG to the load capacitance and the charge dump from the maximum capacitance of the contacted TENG to the load resulted in asymmetric charging behavior. We concluded that it is necessary to analyze the TENG and the capacitive energy management circuit as a single system rather than considering them as independent units in the rectifying circuit of the TENG. This work can provide insights for the design of triboelectric energy harvesting systems.

High‐level voltage and extremely low current are the main characteristics of Triboelectric Nanogenerators (TENGs). Despite TENGs, their Integrated Energy Storage (IES) units like supercapacitors and battery units require low‐level voltage and a high amount of current for self‐charging power applications. Using proper materials with higher triboelectric charge density is the most common approach to enhance the output current of TENGs. However, this approach alone does not satisfy the requirement of the integrated energy storage units, in which a relatively low voltage along with a sufficiently high current is needed. Consequently, alternative approaches such as employing a power management circuitry have been proposed. This paper introduces a technique based on the texture of multiple TENGs with identical small surface areas to adapt the TENGs to their IESs, specifically tailored for wearable electronics. Some experiments are conducted to evaluate the merits and limitations of the proposed approach. The experimental and analytical results are thoroughly analyzed to show the capabilities and restrictions of the method.
