Triboelectric generations are attracting much interests as an electrical power source for electronic applications. Based on dielectric physics, we have proposed a model for triboelectric generators as an energy transfer process from dipolar energy stored in the materials to external electrical load. In this model, changing of polarization is a source of electrical power, and the dielectric relaxation time τ of materials governs I-V. (current source I_s=P₀A/τ, internal conductance G_i=C_s/τ, initial polarization P₀, electrode area A, static capacitance C_s). In this presentation, thermally stimulated current (TSC) measurement for evaluating organic films, e.g., P(VDF-TrFE), for generators is introduced.
