I was actually dreaming about this the other day! I dreamed of a dress a dancer would wear that would have ultra efficient LEDs embedded every inch along with a power harvesting component and as the person danced, the LEDs that moved fast enough would harvest enough power to light up! I also wanted to add basic communication between LEDs so they could somehow be aware of their surrounding LEDs. Probably too futuristic for today's tech.
It was originally inspired by this talk[1] that Tesla's AI chip team referenced regarding the minimum amount of energy needed to perform a calculation.

- waterheater 6y agoA walking pedestrian produces 5 watts per step [1]. A dancer would almost certainly exert more energy, so let's optimistically double that to 10 watts per step. Let's also assume the dancer steps an average of two times a second, for a total of 20 watts of power. Finally, let's assume you're able to harvest all energy from the step. Adafruit recommends 20mA as rule-of-thumb for estimating NeoPixel energy usage at 5V [2], so let's say a NeoPixel requires a little under 1W. You could probably run 20 LEDs during a dance routine in this. While the wireless part is more exotic, it is likely doable. Of course, the form of dance will determine how many LEDs you can include. Perhaps your dancer outfit is best suited for Riverdance...
