Electronics make our life comfortable - we can switch on TV from the couch, check the body temperature in a seconds without mercury thermometer, our kids are happy with flashing and speaking toys, our friends and business are as close as a small cell phone in the pocket.

So the life would be continuing fine - but the batteries.

No batteries - and many habitual toys for kids and for adults also, die. Battery powered devices in industry require expensive periodical maintenance. Militaries are not going to enter the battle with non reliable batteries. Batteries awfully pollute our environment.

Batteries or no-batteries? That is the question!

The man is unable to produce electricity by itself, but expends much mechanical energy while walking, moving hands or fingers and even breathing.
Various objects, devices and gadgets that moves or have moving or vibrating parts can provide mechanical energy that is usually not used and wasted.

Qconverters are one of the solutions that could help to effectively collect and convert this unused mechanical energy into electricity making it possible to design mechanical devices with self-contained electronic "brains" and functions.

It has been demonstrated that with the help of Qconverters:

- electronic door lock can work without batteries using the energy of card insertion, or lever turning.

- LCD flashes and indicates the measurement on self-contained timer when special button pushed just one time.





- Mechanical wall switch becomes a self-contained digital lighting remote control with the distance over 400 meters.
