Is there any chance to get or produce e'city from transiducer by simply placed in pepole walking area like railway station market etc.

If you had a system where, for example, a step would move up (spring) and down (weight of someone stepping on it), it would be possible to use this action to generate electricity.

You mentioned "transducer". If you had a mesh of piezo-electric crystals (for example) that was connected to a walking area, and people stepped on them, you could, in principle, produce electricity.

The magnitude of the electricity generated might be small. Also, the economics of it might not be good (it might cost more to generate the electricity than the electricity is worth, or the capital or maintenance on the system might be too expensive). But, in theory, it's possible to do something like this.

In fact, the technology is called "energy harvesting". There are some wireless light switches that get the power to transmit by the shear action of you mechanically moving the switch. Products are starting to be commercialized.

I believe I had seen a backpack or possibly a jacket where walking could charge a cell phone.
