How the Alcosensor III or IV Works Modern fuel-cell technology (which may power our cars and even our houses some day) has been applied to breath-alcohol detectors. Devices like the Alcosensor III and IV use fuel cell sensors. The fuel cell has two platinum electrodes with a po...
While there are several types oftouch screentechnologies, the two most common are capacitive and resistive touch screens. Let’s explore each of these in detail, along with some other less common types. Surface acoustic wave systems are another type of touch sensor used in touch screen technology...

How Does a Piezoelectric Sensor Works? A piezoelectric sensor sends a signal when it sustains a physical force, which might be pressing, pushing, or changing temperature. Piezoelectric sensors generate an output signal directly from applied stress, requiring no external voltage. The piezoelectric effe...
Who invented touchscreens? Find out moreHow is a touchscreen different from a keyboard?A touchscreen is a bit like an invisible keyboard glued to the front of your computer monitor. To understand how it works, it helps if you know something about how an ordinary keyboard works first. You ...
Most car keys are also portable transmitters. Your key works in basically the same way asradio-controlledtoys. It uses radio-wave pulse modulation to send specific messages. The primary purpose of the transmitter in key fobs is to give you a way to turn your alarm system on and o...
Touch chip, also called touch IC. “Touch” refers to single or multi-touch technology. The touch chip is located between the touch sensor and the PC/or embedded system controller. The chip can be mounted on a controller board inside the system or placed on a flexible printed circuit (FPC...
Your key works in basically the same way as radio-controlled toys. It uses radio-wave pulse modulation to send specific messages. The primary purpose of the transmitter in key fobs is to give you a way to turn your alarm system on and off. After you've stepped out of your car and ...
The transistor works like an electronic switch. It can turn a current ON and OFF. A simple way to think about it is to look at the transistor asa relaywithout any moving parts. A transistor is similar to a relay in the sense that you can use it to turn something ON and OFF. ...
