At present, high voltage and low current are still the representative characteristics of triboelectric nanogenerators(TENGs). So it is not easy for TENGs to lit up a small electronics directly. There are 3 common ways to reach the goal.
1. Achieving energy storge and conversion via a small capacitor.
2. Achieving current accumulation through the series connection of TENGs.
3. Improving the efficiency of contact electrification by surface modification of the friction layers.
The first method is a more practical choice, and the second method also producted some research results. It is worth mentioning that although the current efficiency is still very low, I think the third method still has a lot of room for expansion. For example, the effects of different micro-nano structures and tensile strain on the output efficiency sensitivity of TENGs.
Attached our group 's research on the third method, and I hope my answer is useful to you.

Yes, a triboelectric nanogenerator (TENG) can be used to power small electronics such as LEDs, but it usually requires some additional circuitry to convert the electrical output of the TENG to a form that can be used by the electronic device.
