@debera – The uses of this product is enormous, now you no longer need to carry your travel charger or extra battery pack where ever you go. It's also great if this power could be stored on a power bank for later use.
Elizabeth, can't this principle use the other way around, where the flow will harvest the energy according to the movement of the peoples. If it is applicable it may be harvest more power to a specific work. Like lighting street lamps ..........etc.
Elizabeth this is really really interesting article, these are the innovations that we need in the future. I believe that if each person can produce their day today energy need there want be a much energy issue. This is the ideal way to start that cause that whether we like it or not we walk every day.
"DARPA's effort to harness 1–2 watts from continuous shoe impact while walking were abandoned due to the impracticality and the discomfort from the additional energy expended by a person wearing the shoes. Other energy harvesting ideas include harvesting the energy from human movements in train stations or other public places"
Looks like someone has tried this before.
I would guess that piezo output characteristics are less suitable to battery charging than the generator. Looks like piezo's are good for very high voltages, which is probably not what you want to charge a cell phone battery.
Festo's BionicKangaroo combines pneumatic and electrical drive technology, plus very precise controls and condition monitoring. Like a real kangaroo, the BionicKangaroo robot harvests the kinetic energy of each takeoff and immediately uses it to power the next jump.
