Piezo Vibration Energy Harvest

Hi! How would you suggest mounting the piezo vibration sensors on a guitar to output to an energy harvester, then send to LED lights around the body of the guitar? I was thinking multiple sensors, but would probably need to clamp them to jump wires for a strong connection. I was originally going to use the round piezo transducers, but when I saw the little vibration ones they looked like they could mount closer to the strings. Any ideas on linking multiple transducers to output to the LED’s for a higher continuous current? I was originally going to mount harvester, etc on the back of the guitar to keep my hands off of it, but the wires from the piezo sensors would be quite long. The lights are “battery operated” led tape lights. My plan is to get rid of the battery case (cut the wire) but keep the current in-line controller because it works with the remote. They shouldn’t use much power, especially once I cut them to length around the body of the guitar. The goal is to light the LED tape strip with the strumming of the guitar.

Future projects might include eliminating the controller and programming the LED’s myself, but am limiting scope of the first round of the project to getting the energy harvesting aspect up and running to just light the lights. I plan on linking more than one piezo sensor, but the ones I see are designed to plug directly into the breadboard. Might try mounting them up close to the strings like a regular pickup does.

To increase the current you’d need to wire several harvesters in parallel, all of their outputs going to the LED chain (each harvester is rated for 100mA max, so depending on how many/specs you may want to change the number/color to help reduce power requirements). You can use batteries or a power supply and a multimeter to determine how much power the LEDs want

For the other stuff: like you said it’s a good idea to get something working first, then worry about mounting/wiring and whatnot

Here are the lights I hope to be running. I think we will cut off the last few lights, maybe a foot.Amazon.com: GOIEHIR LED Strip Lights Battery Powered, 24 Keys Remote Control Light Strip for Parties, DIY Indoor Decoration, 6.56ft/2m : Tools & Home Improvement

By several harvesters, you mean several piezo sensors leading to the harvester, right? Then could I run it through a booster? Thanks @TS-Russell I appreciate the response.

Both, depending on power requirements…you might need a few sensors each on a few harvesters (each harvester can only push 100mA)

Experiment first, before committing to any design.

Otherwise you may be pretty disappointed in how much energy can realistically be harvested, how many LEDs you can blink, and how brightly.

Thank you, yes. Determining how much can realistically be harvested per piezo transducer. They use them on electric guitars, but not to generate electricity. Maybe I will have to reduce the numbers of LED’s. I’ve seen someone do them with just a few with 3 round transducers.

Do you think I could use these SKU: SEN-09197 instead of these SKU: SEN-10293 ? Plus an alternative might be to use a battery as well and use the sensors/transducers to “charge the battery” that supports the lights in addition to boosting? Does that sound more do-able?

Sure - these are all inexpensive enough that you might want to grab a variety of items and perform real-world testing to see which arrangement makes the project most viable
