i find such research efforts mundane rather than breakthrough. We know the properties of piezo-material but the efficiency and the impact is quite little. Until and unless we can generate some significant energy from daily mundane task; we are not going anywhere.

You make a good point. The fuel efficiency of an automobile on the piezo-road goes down, because the car is doing more work. That's what happens when you switch the aircon on in the car. In effect it could be a skimming tax that gets all the cars to do a little bit of extra work to reduce the municipality's cost of electricity. There is a distinction to be made between energy harvesting that would otherwise be wasted and adding to the work load.

I actually been toying with similar ideas for a number of years now. While individually, each device would only generate a minimal amount of energy, collectively they could provide an adequate amount of power. There are literally thousands of places we could siphon off a little bit of this wasted eney. Walking, riding a bicycle, capturing heat from a stove, typing, even opening a door could generate small amounts of power. As engineers, I'm sure we could even harvest enegy from the gravitational pull of moon or the rotation of the earth. The biggest hurdle at present is cost and the limits of our imagination. And yes, there already exists fitness clubs that harvest energy from stationary bicycles

and yeah this would solve all our energy problems. I mean who would spend extra money and time if one can just plug in the device to the main outlet?

The amount of power generated is too low. At best the idea may be useful for extend battery life of desktop wireless keyboards running on a rechargeable battery. BTW, If they make it work, then people have to push the keys harder, which consumes more energy from the user, which makes them consume more food to replenish.. back to square one. food to energy. what is conversion efficiency? 5%? People had the same complaints about Israel's Piezo road and Tokyo's Piezo floors :) http://www.gizmag.com/piezoelectric-road-harvests-traffic-energy-to-generate-electricity/10568/ http://www.celsias.com/article/foot-powering-tokyo-train-station/

we can harness energy from analog engineers also, i think it can be best done with a track ball mouse based on the movement of the ball we can generate energy and by placing a thin film near the mouse click this can be achived . ...

This is definitely an interesting study. I'm surprised that the study doesn't mention anything about PC laptop and desktop keyboards which probably generate more power and require less power than touch screen keyboards. Also, touch screen keyboards are just pieces of code that appear and not physical keys, so I would love to learn more about the functionality of piezoelectric thin films. Currently, smart phones, for example often have a terribly low battery life. So, I agree with Salio above that this very simple interaction could be a huge breakthrough. It reminds me of self-powered mechanical watches.

Interesting article. Using typing to charge continuously charge your laptop or wireless device. This would be big break for the smart phone industry. My Sensation battery sucks. If I run 4G on it, it will drain the battery in about 2 or 3 hours. If I can continuously charge the battery as I am using the phone, heck running 4G is not an issue. This would be amazing.

When keyboards itself have started vanishing from the portable devices such as mobiles and tablets , to do research on energy harvesting using keyboards is itself a waste of energy. There could be better ways of energy harvesting from our body movement such as walking, cycling and so on
