The optimisation of the T-TENG results in a final design that includes MoS2 on one side and a 5.5 mm thick spacer. The tribo-layer, composed of an insulator-coating material, is kept at an optimal thickness of 57μm. The Voc of the optimised T-TENG was explored in relation to different forces to assess its potential for integration into diverse wearable positions like elbow joints and shoes or socks. Increasing the force on the T-TENG led to a significant rise in output voltage, with the device achieving an output voltage exceeding 1070V at a force of 22N (Figure ). Additionally, the response of the T-TENG to various frequencies was investigated using a 10N force, revealing a slight increase in output voltage with frequency. An increase of 1.2 times was observed up to 8Hz compared to 1Hz, but there was very minor increase above 9 Hz (Figure ). These results emphasise the T-TENG's potential for implementation in various wearable applications, offering the ability to harvest energy during activities such as walking, running, cycling, and more. and). The power density was computed and found around 14.64 W/m 2 (Figure ). Numerous studies have found encouraging findings for textile-based triboelectric nanogenerators (TENGs). Notably, the findings of this study stand out as having the highest reported values among cotton fabric based TENGs. To support these findings, a comparison table ) is presented, which includes results from previously published publications on T-TENGs. Investigating the T-TENG's response to different resistive loads, measurements of rectified voltage and power densities were conducted across a range from 1MΩ to 100MΩ. A linear increase in both power densities and voltage was observed up to 50 MΩ; however, a further increase in the load led to reduction in power densities (Figure ). These characterizations demonstrate the potential of T-TENGs for applications requiring high loads.

In accordance with CV results, GCD for the developed T-Supercap was measured across current densities from 0.33 mA/cm 2 to 1.0 mA/cm 2 , revealed triangular-shaped curves with nearly identical charge and discharge times, akin to an ideal double-layer supercapacitor (Figure ). The calculated areal capacitance for a scan rate of 10 mV/s was found to be 4.9 mF/cm 2 , which is more than the recently published results in ref . To showcase the flexibility and stability of the device, the CV curves of the supercapacitor were measured while bending at various radius of curvature. Negligible effects were observed compared to the flat mode, indicating that the developed textile supercapacitor can be effectively employed for wearable applications in various positions on clothing (Figure ). To assess the electrical combination response of the developed T-Supercaps, GCD curves were recorded for both a single supercapacitor and three supercapacitors in series. It was observed that for an equivalent charging time, the three supercapacitors in series reached 1V, while a single T-Supercap charged up to 3V. This confirms the linear and consistent behaviour in the fabricated supercapacitors, as illustrated in Figure . The durability of the developed T-Supercap was validated by a cyclic run of GCD with a current density of 0.33 mA/cm 2 for over 1000 cycles. A minor reduction was observed, maintaining more than 96% capacitance retention (Figure ). These results highlight the potential of the developed T-Supercap for efficient energy storage applications.
