Piezoelectric Actuator Testing: Displacement vs Voltage
HTML-код
- Опубликовано: 11 сен 2024
- In this video I introduce stacked piezoelectric actuators, and test one to see how well its displacement vs voltage behavior compares against the spec sheet. This particular device, the PK2FSP2 from Thorlabs, cost roughly $100 and produces a displacement up to about 25 um at 75 volts.
I don't know about this, but I'm just glad SOMEONE on the internet knows how to correctly pronounce 'piezoelectric'.
I was very intrigued by this, and have a few applications I would like to apply this to. Would love to see more content on this channel.
Oh I'm sad I'm late to get on this channel and it seems it's no longer active. I loved this video!
Thanks for this clear easy understand presentation
Can you please tell me the calculator short key for what you did at 4:30? I have the TI-84, but I was wondering what you did to show those calculations consecutively.
Did you test it in reverse polarity??
The piezoelectric actuator still make displacement or damage ?? Please reply
Hey man, did u expirience and damage from using it without a preload? And after your Experiment, how did you discharge the piezo stored charge? Did you already implement it in an exoerimental setup? If ja kindly share. And while increasing voltage, u expirienced now currect increasing? Would that increase? If piezo is under load?
When exposed to sili, does the crystal accumulate a charge in its capacity?
How surface area and geometric structure affect the over all voltage?
After watching this my only thought is: "And then..."
Did you get to use the actuator?
nice
Can you, please, specify the power consumption of the actuator ? TY !
what is the strain @75V? like 0.001?
Very useful
4:05 Emotional loads xD I mean Piezo's have a bad rep. They just need some love. Hysteresis got 'em bad.
Did i hear correctly? "Emotional Loads"
"Never any tension, torque, shearing or emotional load"
How bout that teledildonics???
Time for the generated force video
4:05 Emotional Load. 😀
Today’s scientists have substituted mathematics for experiments, and they wander off through equation after equation, and eventually build a structure which has no relation to reality.

And what relevance does this quote have to this video?
@@nickstanley5064 the quote itself has nothing to do with the video. It served a different purpose.
@@Johnkent1965 , and that purpose would that be?
@@nickstanley5064 tôi cho bạn một gợi ý: nếu tôi nói cho bạn biết ý nghĩa, nó sẽ mất mục đích.
@@Johnkent1965 , I didn't ask you about the meaning of the quote, I know what it means. I'm asking you why did you use that quote in the comment section of this video.
Are you using that quote to criticize the guy in the video for using a bit of mathematical modelling near the end?
Stop with the laziness; post Whatever!
