A force applicator was developed in the laboratory using CNC and 3D printing machines. It incorporates a mechanism to convert rotary motion into linear motion using a 24V DC motor, facilitating the exertion of force on the T-TENG. To measure the exerting force a commercial force measuring device was utilized in parallel (Figure , supporting information). The output voltage was measured using a Tektronix TBS1052B oscilloscope, while current measurements were taken with a Keithley DMM 7510 multimeter. Rectifier and voltagedivider circuits were constructed in the lab for this purpose. For the electrochemical characterization of supercapacitors, an Iviumstat electrochemical interface was utilized. In the application for step counting, an Arduino UNO controller was programmed and interfaced with a desktop application developed in Python. Additionally, the surface morphology of fabricated layers was examined using an FEI Quanta 650 field emission scanning electron microscope (SEM).
