Advancement of wearable/attachable devices requires the development of corresponding energy supply devices. Triboelectric nanogenerators(TENGs) are being proposed as these energy supply devices. The reported stretchable TENGs are fabricated using a stretchable electrode layer. And, these stretchable TENGs have a disadvantage in that the characteristics of the device are limited by the electrode layer. In this work, we have developed a skin-attachable single layer PVC gel TENG and position sensor. The PVC gel was prepared using biocompatible plasticizer dibutyl adipate (DBA), and not only increased the flexibility, but also increased dielectric constant, transmittance, and reduced electrical resistance. The output performance of the single layer PVC gel TENG and its output stability with high strain were evaluated. Also, we demonstrated a position sensor that uses output difference as a function of the distance between the electrode and the contact point.
