PIEZO BUTTONS FREE

Those handle the negative voltage that would destroy the pins/chip. I made this work for a button that senses press on one pin and release on another.įirst connect diodes from ground to each lead, pointing from ground to the lead. Piezo when pressed makes one lead + with respect to the other, that force can make current flow one way.īut when you release pressure, the flow goes the other way. Could it turn on a transistor or should I convert some voltage to current or any other problem. We understand how confusing it can be, learning about new technology and as such, will gladly talk you through all of the specifics in order to paint a clearer picture for you.How do I use a piezo disc as for atleast turning digital value to 1 or by using a transistor.

If you’re interested in learning more about how piezo technology can be applied to your industry, then please feel free to contact us today. Would you like to know more about how a piezo switch can be applied to your industry?Īs we advance even further into our technological aptitude, there are more and more incredible feats of engineering being brought out and applied in both the consumer and private sectors. You’ll get an awful lot of usage out of them as well, which is another very important thing to take note of. Hopefully, what you will have taken away from this piece is that piezo switches are incredibly versatile, durable and easy to apply in a wide variety of industries. Understandably, it’s an awful lot of information to digest, so we will aim to bring this piece to a close without forcing too much on you. A quick look at piezoelectricity in industrial applicationsĪ quick look at piezoelectricity in medical applications With piezo switches, they can endure much pressure and significant usage, so you’ll never have to worry about the functionality of a switch failing on you. The last two points (no wear & tear and weather resistance) is particularly important for those in the mining industry.

Damage and weather resistant (being able to be completely sealed off from the environment).

No wear & tear (ensuring tens of millions of operations).

Diverse application capabilities (the Mining, Aviation, Medical & Transport industries to name a few).

No external power source required (given that they produce voltage when pressure is applied to them) That said, piezo switches have a low output compared to other counterparts, so an external power source may often be required for optimum levels.

No moving parts (only the pressure plate, requiring one simple press).

When compared to conventional mechanical switches, piezo has some wonderful advantages… What are the advantages of using a piezo switch? As such, they can be useful in a wide range of industries and applications. So, from these two comparisons, we can deduce that piezo switches are incredibly versatile, functioning under extreme pressure and the slightest anomalies. The piezo material can pick up the slightest disturbance, which is why they’re invaluable when applied to medical imaging & industrial non-destructive testing. (i.e., the “hammer” is replaced with a different form of energy such as a sound wave). Now, when applied in sensors, a very different approach is used. Let’s look at the way in which piezoelectricity is applied to electric lighters: pressure is applied to a button, a hammer strikes a piece of piezo material and then a spark is created from the force to produce a spark, thus lighting a flame. For now, let’s look at the way in which they can be applied in sensors and motors. Piezo switches are incredibly diverse and durable, but we’ll get to the benefits soon enough. But how can piezo switches be applied to your business? Which industries can benefit from it the most and why? Piezoelectricity in sensors and motors These are just a few examples of everyday items which adopt piezoelectricity. If you recognise the following items, then you’ve witnessed piezoelectricity in effect: Where can piezoelectric materials be found? The phenomenon was discovered by French physicists Jacques and Pierre Curie in 1880.

Piezoelectricity is an electrical charge which responds to mechanical pressure in solid materials (e.g., ceramics, crystals, various proteins, bone and DNA).

Piezo is derived from the Greek word piezein, meaning “to squeeze” or “press.” So, essentially, you could call it a “pressure switch.”.But before we do, let’s break down the name for a better understanding… A piezo switch is a type of electrical switch which is based on what’s called: the piezoelectric effect, which we’ll cover in detail for you in just a moment.
