TENG parametric characterisation

This repository contains the data and code behind a parametric study of a contact–separation triboelectric nanogenerator. The TENG itself is simple: a PTFE dielectric with copper-tape electrodes, pressed against interchangeable counter-electrode materials by a custom belt-and-pulley test machine. Seven parameters were varied: counter-electrode material, dielectric thickness, surface roughness, contact area, impact speed, separation speed, and humidity. There is also a separate charge build-up experiment. The processing pipeline takes raw oscilloscope waveforms, reduces each acquisition to summary statistics, screens for outliers, collects everything into manifests, and generates the figures used in the publications. The work was carried out at the Department of Mechanical and Industrial Engineering, NTNU, Trondheim, and supports two papers currently in preparation: Parametric Characterization of Triboelectric Nanogenerators (IEEE Access) — based on the dataset and analysis code in this repository. TAP: TENG Actuation Platform — A low-cost, contact–separation Triboelectric Nanogenerator characterization Jig (HardwareX) — describes the test machine itself
