The response of a linear system can be decomposed into zero-input response and zero-state response. The zero-input response is the system output when the input , and thus it is the result of internal system conditions (such as energy storage, initial conditions) alone. Understand the zero-input behavior provides interesting insight into a system.
The zero-state response refers to the output of a system that results solely from the input signal , under the assumption that all initial conditions of the system are set to zero. 1 It can be modeled as the convolution of the unit impulse response and the input :
Furthermore, energy storage technologies effectively address energy supply intermittency issues, leading to additional reductions in operating costs and the carbon footprint.

The ZSR is the system’s response due only to external inputs, assuming all initial conditions are zero. As shown in Figure 1 A, conventional TENG discharge is primarily driven by external excitation and can be considered as a ZSR.
Based on the preceding discussion, in this section, we propose a circuit-free design for quantitative charge output control of a TENG via the design of synchronized switches. This design generates a quantified voltage signal across a capacitor (serving as a sensor to receive external inputs) within 10 V, which can be directly collected by a DAQ.
Unlike conventional synchronized switch designs aimed at charge accumulation for enhancing instantaneous outputs, our work uses mechanical switches to regulate the zero-input (ZIR) and zero-state (ZSR) responses of TENGs, generating outputs with clear and repeatable patterns.
