Even though the circuit uses smd components, construction of the touch sensor switch is not very hard because the whole circuit can be easily fabricated on a piece of smd prototyping board. At the ...

Watchdog Timer Enables Capacitive Touch Sensor Sept. 24, 2009 A simple four-component circuit allows a single I/O line from any microcontroller to sense the states of two capacitive touch sensors.

Sixteen-key QT60160 and 24-key QT60240 touch sensor chips will sense the touch of a finger through panels of any electrically insulating material. Panels can be 50 mm or more in thickness when used ...

We will then contrast theoretical vs. real-world amplifier performance, and give examples of how commercial chips specs are interpreted. Then we will discuss the causes of noise in sensor circuits, ...

TEST CIRCUIT AND PCB One example of a water-tolerant touchsensing system is based on Cypress Semiconductor’s CY8C21434 PSoC chip . 2 This design includes three touch sensors that are labeled ...

This patented integrated circuit invented by Shreyas Sen and his students was among the first of their chip designs inspired by the human body. (Purdue University photo/Kelsey Lefever) “If we want to ...

Chips Implement Sensor Signal Chains From Nanoamps To Bits Feb. 11, 2011 Other chips have integrated a signal-conditioning AFE with an ADC, often for medical imaging.

“In addition, it is easy to expand the circuit boards to later include other sensors, for example, pressure.” Right now, the researchers only have a small, 15-chip array on a robot arm.

The promise of the Internet of things is, in a sense, passivity. Our homes and offices will monitor us, and respond to our needs without instruction. But for tiny wireless sensors all over us and ...

(This Oct. 23 story has been corrected to change references to IC (interface controller) from fingerprint touch ID. This version has removed background paragraph on touch ID) ...
