Sense Magnetic Fields Like a Bird – Sensory Extension Puppet

This project will show you how to create a computationally enriched puppet that can detect magnetic fields. The puppet (who I call Compy) has two very sensitive GMR analog magnetic sensors that are located in her beak, these sensors are read by an Arduino Nano that actuates a 3×3 haptic display (Figure 3) based on …

Inside the Intel RealSense Gesture Camera

The Intel® RealSense™ gesture camera represents another foray by Intel into the consumer products space. The camera has been incorporated into the Lenovo ThinkPad Yoga 15.  Intel disclosed at IDF14 that the device is formed using three components: a conventional color CMOS image sensor camera, an infrared images sensor, an infrared light projector (the main focus of …

Current-sense amp integrates precision shunt resistor, in single package

For highly accurate measurements over a wide temperature range, TI’s INA250 integrates the shunt resistor with a bi-directional, zero-drift current-sense amplifier to support both low-side and high-side implementations. It enables high-accuracy current measurements at common-mode voltages that can vary from 0 to 36V. The family of devices will be available in four output scales; 200, …

Electronic skin can sense the direction in which it’s being touched

We’ve already seen artificial skin capable of sensing touch and prosthetics that sense texture, but now a group of Korean scientists has come up with a stretchable electronic skin that “feels” in three dimensions. The artificial skin is made from arrays of microscopic domes that interlock and deform when pressed. It can detect the intensity, …
