energy into electricity was investigated. The finite element analysis simulation was
performed to illustrate the influence of surface engineering of the Al-PTFE TENG on
electrostatic properties, especially at the edges of the TENG. The triboelectric performance
of the TENG was improved through surface modifications of the PTFE using low-pressure air
plasma treatment. The output voltage increased from 13 V in the untreated sample to 90 V in …
