Hey Shabaz! Thank for this new piece of experimental knowledge. [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-c5647914-55d0-43fd-8b2c-bbefb2d9f77f/7853.contentimage_5F00_1.png:16:16]

This post is very helpful, I have some of these around and for now, as I have no time to make tests I have just bookmarked the article. Very clear and super useful.

Pvdf sensors have high impendece why??? And how to reduce it

May I know d reason of the sensor to b dis sensitive that even an air causes it to sense and how to avoid it

hey,

i am working on a project wherein i am about to develop a mechanism as when you run on a Platform it gives scaling on the screen placed up. the more you run on that platform the screen showcases the increase in percentage scaling from 0 to 100% . Can this concept be developed using this sensor adn enablng it to the arduino board

I would be much obliged if you could help me on this ASAP.

Thanks and Regards:

Aman sharma

what is the max output current that i can get from the 5 inch long piezoelectric strip, the output voltage max is coming to be 21V at 60 Hz vibration from shaker, any body can help me, i have to connect it to LTC 3588 demo board which says the input max current has to be less than 50 mA, so can i connect the piezo strip directly to its input, or i have to insert a resistor in series. because inserting a resistor is causing drop across it. some one can help me.

For the past few days I was trying to figure out, what sensors are used in the babies breathing monitors (to quickly react in case of a Sudden infant death syndrome). They seem to use a simple piezoelectric transducers, which can be found for example in sound-playing birthday cards. Then I found this post thanks to Doug's latest reply. This sensor looks like an alternative - the same principle, but a bit different physical arrangement.

Hello,

Have you tested this sensor only with the oscilloscope?

I'm interested in connecting this to an Arduino/Beaglebone/other board and use it to trigger some action, like recording a video.

Do you know if I can connect it directly to one of the analog pins?

Thanks,

Daniel

Does it come in 20M by 20cm size and would it respond in less than 100uS or thereabouts ?, oh an dis it cheap ?.

Looking at ideas for my summer project [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-c5647914-55d0-43fd-8b2c-bbefb2d9f77f/contentimage_5F00_1.png:16:16]

Very nice article Shabaz, The output voltage is certainly amazing making it easy to attach to micros etc.

You mentioned the fact that the device is sensitive to heat from the soldering process, would it better to crimp a set of ends onto the sensor ?

Very interesting blog.

I thought of a number of potential applications, including rain gauge, thunder detection, energy harvesting, plus a host of movement detection sensors.

Now if I only had some free time to play.

Thanks for posting on this very interesting sensor technology Shabaz. I have some of these sensors equipped with small masses on the far end (away from the connection points). It is easy to get >60 V output signals by flicking the mass with moderate force. My plan is to try to use these sensors to create an anemometer and wind direction sensor that has essentially no moving parts. Signal conditioning and processing would be challenging, but I think still within rreason.

Good article,

They can definitely generate high voltage - I have a demo strip lying around somewhere that is hooked directly to a neon light - it lights up when the pvdf strip is waved back and forth rapidly. You are right - the number of applications is too large to describe in a short article. One whole other range of applications, as I'm sure you are aware, is to use the material as an actuator or speaker since it deforms when a voltage is applied - in case someone wants too explore further.

Nice work.

The bent result surprised me.
