    Hello CEans,
    I think, the energy wasted as vibration, when a vehicle moves, can be converted to voltage using vibration sensors and can be used for charging mobile phones etc. Well I want your help to improve this idea. We can use a vibrational sensor (piezoelectric crystal) to convert vibration to voltage. Then we can use a voltage regulator and save excess energy for making up the low voltage when low vibration is there. I dont know whether it is possible to save excess energy. pls help.

    Thank you
    Manoj

    Manoj, welcome to CE. Good idea 😀 . Could you elaborate your idea a bit in more detail?

    can we use vibrations to generate electricity for our homes and industries?

    i heard when pressure is applied to such materials...voltage isdeveloped
    till the pressure completely disappears
    ..does this implies ,voltage is generated continously?????

    I dont know to how extend this vibration will grow
    Any way if you have some idea we can discuss.

    Yes, we've been continuously discussion the usage of vibrations into other forms of energy. Try checking these other threads for some other ideas:

    Perhaps you might have some technical suggestions and more practical ways to implement it? We are all eagerly waiting for a great solution 😀

    Oh thanks Well I will look forward to findout a practical way for this

    I must say that all the engineers associated with CE are really genius & if anybody isn't then He becomes after joining it.
    thank you CE-team.

    Think what happends when pressure isapplied continuouslly. I mean in periodic manner.

    Can't we use a spring (which can store this vibrational energy into potential energy )and use it for later use???
    sorry if it was a foolishness because i am just a beginner.😲

    How can a spring store energy?

    In general it is not practical to recover vibration energy. Consider, as an example, an auto travelling on a highway that has undulations of 0.1 m up and down about some mean elevation. When the auto hits one of the "up" bumps, some of that energy can be stored in a compressed spring. Of course, the spring exerts a force on the auto, thus, storing some of the energy in upward kinetic energy. When the auto then strikes a "down" bump, the energy stored in the spring can be recovered to push the wheels down; however, the larger mass of the car may still be rising? The point is that, unless you have tuned the spring and car to a particular road, you will run into some nasty vibration modes. Further, note that you needed to get back that stored energy in the springs. Bottom line, good auto rides really need dissipative spring action (damping) and, if your roads have lots of vibration, it's better to smooth them and save the energy that way.

    Oh I dont know to that extent. Its actually a funny idea. In our land KSRTC buses mainly gives high amount of vibration. Anyway thanks
