A long-winded look at the trials and tribulations of triboelectricity, with a brief sally into silly sculpture:
And videos of the serious research parts of the project:
(Just the TENG, no capacitor, no load, spiking around 10-15 volts per whack)
(The TENG with .1uF capacitor, smoother charge/discharge curves of around half a volt)
(The TENG with .01uF capacitor, broader peaks of around 3 volts, and then with an LED load)
(Multi-Layer TENG with .01uF capacitor, with and without LED, showing a little more power but still no visible light from the LED)
And a video of the baby, because why not?
