datacite.description.methodThe short-circuit current of the TENG was measured with a transimpedance amplifier circuit with an amplification factor of 2.000.000 and the ADA4530-1 operational amplifier. The acceleration data was measured with the ADXL354 acceleration sensor with a measurement range of ±8 g. Force data was measured with two load cells and instrumentation amplifier circuitry. Temperature and humidity were measured with the HDC3120 sensor. Surface area roughness was measured using a laser scanning microscope (LSM, Keyence VKX3100). At a magnification of 500x (50x objective lens, 10x ocular), a total area of 6.3 mm2 was scanned. The measurement consisted of 100 individual images arranged in a 10 × 10 matrix with a spacing of 1 mm between the images. The arithmetic mean height Sa was calculated with the Keyence VK-X 3000 MultiFileAnalyzer software according to ISO 25178. The S-filter nesting index (S-Cutoff), which acts as a low-pass filter for measurement noise, must be at least three times the lateral measurement resolution and should be set to standardized values which can be found in ISO 25178-3. All images measured 289.381 μm x 216.965 μm with a resolution of 1024 x 768 pixels, resulting in a lateral measurement resolution of 0.283 μm/pixel. Consequently, the S-Cutoff was set to 1 μm. Subsequently, a planar shape correction (F-operator) was applied, compensating for the slight tilt of the stage. The L-filter nesting index (L-Cutoff), which is typically used to correct the surface waviness (high-pass filter), was not applied since the PTFE and the PI exhibit no distinct structural wavelength, and the wavelength of the aluminum could not be determined unambiguously. For each material, the resulting Sa values of the 100 measurements were averaged, and the corresponding standard deviations were calculated.N/A

dc.description.abstractIn this study we investigate the remaining variance of the triboelectric output under controlled process and environmental conditions. We use a lateral sliding configuration with polyimide (PI) and polytetrafluoroethylene (PTFE) foils acting as triboelectric layers against an aluminum (Al) foil. Long-term tests of one hour are conducted followed by a parameter variation of sliding rate and applied normal force. Micrographs of the surface are used to gain a rough estimate for the effective contact area. This data provides the raw measurement data of short-circuit current, acceleration, friction force, normal, force, ambient temperature and relative humidity. In addition, the raw data from the laser scanning microscopy of all specimen prior and after testing are provided.N/A
