可拉伸摩擦电纳米发电机（s- teng）是一种很有前途的自供电可穿戴电子设备电源。传统的单电极s- teng需要一个外部接地电极来形成一个闭合电路。我们提出了一种基于差分表面功能化的平面内双电极s-TENG，以消除外部接地电极。s-TENG包括完全可拉伸的材料，如碳纳米管薄膜和弹性体。弹性体的顶部表面被功能化，以产生两个电极区域之间的电负性差异。通过手工轻敲两个电极区域，获得了3.5 W m（-2）的高输出功率密度。
Stretchable triboelectric nanogenerators (s-TENGs) are promising power sources for self-powered wearable electronics. Conventional single-electrode s-TENGs require an external ground electrode to form a closed circuit. We propose an in-plane dual-electrode s-TENG based on differential surface functionalization to eliminate the external ground electrode. The s-TENG comprises fully stretchable materials such as carbon nanotube thin films and elastomers. The top surface of the elastomer was functionalized to produce a difference in electronegativity between the two electrode regions. A high output power density of 3.5 W m(-2) was obtained by tapping the two electrode regions by hand.
