Do you remember the last time you played a video game or saw, in real life, somebody using any type of touch screen device as smartphone or tablet? Then congratulations: You have already experienced the sorcery of piezoelectric sensors! These little sensors are powerful enough to actually perceive pressure and vibrations of any form which will only be explored today from part 2 so as to not make this article too long. It results in improved firsthand experiences with the devices.
Piezoelectric sensors are so called because they respond to pressure or squeezing—the word piezo from Greek means press/ squeeze. They are based on a specific type of crystal that is capable to generate electricity when pressure or vibration applied. Every time we press these sensors, a small electric charge is created. This small fee will assist the sensor in understanding how much pressure was applied by us. Almost like a little assistant which commands the device how hard we are pressing!
However, piezoelectric sensors are here to change how we see touch technology in an even greater fashion. You can find, for example the Windows driver of modern game controllers we use to play video games. In an action game, the sensors fire off as well which is key to making the feel of hits or jumps have some sort of connection. It can also work with touchscreen, which makes it possible that we control our devices just by tapping and swiping or scrolling through the screen. All of this makes technology enjoyable and convenient to use!
Piezoelectric sensors are utilized in hospitals as a founding technology for aiding doctors during surgery. The sensors tell doctors how hard they are pushing while working on a patient. The pressure-sensing capability enables greater control and feedback preventing mishaps on surrounding locations. It is fascinating how and small sensors can improve liveability of people, but actively prevents potentially fatal accident in a medical procedure!
Haptic feedback is a term that refers to the way in which we experience objects through touch or physical manipulation with technology. And it is all about how we feel these sensations through our fingers. Piezoelectric sensors play a very important role in making this touch feedback the best it can be. The easiest way to get started with that is helping designers create an engaging user experience.
We are on the path to develop smart piezoelectric sensors for an impressive variety of applications that better our everyday lives. In automobiles, these sensors can detect whether someone is applying pressure to the steering wheel. This data can be used to alert drivers of potential hazards at the location or even slow down traffic whenever necessary for safety reasons. Its as if you have an additional pair of eyes watching the road!
Among the applications being tested is for safety and security checks of airplane wings, parts etc in aircraft industry using piezoelectric sensors. Even before they turn into something serious, they are able to sense vibrations or strain. This makes certain far better management of the condition helping maintenance crews correct slight troubles, well before they become significant safety issues that could jeopardize passengers throughout their air travel.
