Triboelectric　nanogenerator　(TENG)　technology　is　an　emerging　nanotechnology　with　potential　applications　in　energy-harvesting　electronics,　self-powered　electronics,　high-voltage　electronics,　and　other　smart　electronics.　Electronic　circuits,　such　as　power　management　circuits　and　driving　circuits,　play　key　roles　in　the　applications　of　TENGs;　thus,　because　simulation　is　the　most　efficient　and　cost-effective　way　to　design　a　circuit,　the　need　to　design　TENG-related　electric　circuits　through　circuit　simulation　rather　than　through　experiments　is　urgent.　However,　as　power　sources　with　unique　output　performances,　TENGs　do　not　exist　in　the　device　libraries　of　commonly　used　circuit　simulation　software,　which　prevents　circuit　designers　without　TENG　expertise　from　designing　TENGrelated　circuits　and　hinders　the　widespread　development　of　TENG　technology.　In　this　work,　we　construct　a　TENG　module　based　on　the　vertical　contact-separation　mode　in　commercial　MATLAB　software.　The　simulated　outputs　of　the　constructed　TENG　module,　including　voltage,　current,　power,　and　load-dependent　characteristics,　are　in　good　agreement　with　theoretical　results.　Furthermore,　we　utilize　this　TENG-like　power　source　to　study　the　charging　efficiency　of　a　capacitor　in　a　resistor-capacitor　series　circuit　and　demonstrate　the　interconnection　with　other　application　modules.　The　results　of　this　work　will　allow　load　circuits　for　TENGs　to　be　more　easily　designed　by　using　computer-aided　circuit　simulations,　which　is　of　great　significance　to　the　development　of　TENG　technology.
