Are there any alternatives to piezoelectric transducers?

I saw a post about an energy-generating device on shoes which generates electricity when walking. Piezoelectric transducers were used to generate energy but not enough to charge the battery full or even half full. Are there alternatives to Piezoelectric transducers that generates more energy than piezo? Thanks.

Bite force transducer embedded in a gumshield

I am a quadriplegic and paralysed from the shoulders down. I am working on a project to allow me to control a go kart. I have limited use of my arms which should allow me to control the steering but I am trying to get another degree of freedom to control acceleration and/or braking One of the ideas is to use a piezoelectric type force transducer in the mouth to control and acceleration via an arduino or similar. The transducer would detect bite force and it would be converted into control signals for the throttle and/or brake. It would be embedded in a gumshield and it would be acceptable to have a cable coming from the front of it to the control System. I am wondering has anyone worked on such a project and could anyone point me in the right direction please. The gumshield may end up looking something like the image here.

smoke detector piezoelectric transducer hack?

I'm thinking of building a basement water leak detector like this: I wanted to hook it up to something loud like a smoke detector. Is it possible to take adapt the piezoelectric transducer circuit with the water sensor? Any guides. Thanks

HAARP mind control?

Allegations have been made that the HAARP project is behind mind control experiments. The ex governor Jesse Ventura, interviewed a professor who demonstrated in his show that it is possible to send messages to people's minds without any need for hearing. The professor put two piezoelectric transducers on Ventura's chin and Ventura claimed to be able to "hear" music in his brain. Real science or pseudoscience? If this device could be made, wouldn't this device help people without hearing? What about the possibilities of learning devices or communication? I believe that this device could put thoughts on people's minds but not necessarily control them (unless it is an easy suggestible subject). Please watch a segment of the show and share your opinion:
