As we all know, manufacturing machines whilst in operation produces unwanted noise and vibrations. These are the forms of energy that is usually lost. Is there any possible way as to using a piezoelectrical device to harness this energy? If this is possible, then the same energy can be used to supply partial electricity to the machine thus saving some energy and finally saving money.
Dear Krishneel,
This is possible and we have already treat a similar issue but for human being. Enclosed, you will find a paper dealing with this.
Hope this could be helpful.

Dear Krishneel,
Of course, it is possible. I studied some sensors to produce my works and one of them is the piezoelectrical. The vibration of the manufacturing machines will serve as the source of energy that will be transduced to current. The question is if the energy generated by this scheme will really help in this manner or if the energy generated will be so low that could not cover a necessary level to the machine normal working. The number of phases should be considered too and if the machine is CA or CC. If it demands conversions, so a minimum of current should be obtained from piezoelectrical components. So, the intermediate block between piezoelectrical sensors and manufacturing machines is important.

Dear Krishneel,
It is wonderful idea. Certainly piezoelectric sensors will produce output voltage, but very small magnitude and it is of DC in nature. You can use converter and boost the magnitude using suitable electronic circuit.

Dear Krishneel
Yes, I agree with all the the 4 answers above, but piezoelectric actuators can convert energy between electrical and mechanical not just from the mechanical energy to a DC voltage output as you are working on now.
It is true that piezoelectric sensors produce output voltages with very small magnitudes, so you need to boost the magnitude by using suitable electronic circuits or buying suitable converters.
I have done the research using piezoelectric actuators for a nano-positioning system if you are interested in having a look at it "Robust H∞ control in nano-positioning" on the RG link https://www.researchgate.net/publication/260586854_Robust_H_control_in_nano-positioning.
Hope it helps. Good luck
