SkinTrack Controls Your Smartwatch with Gestures on Your Skin or Clothes

A group of researchers of the Future Interface Group, Carnegie Mellon University in the US, has worked on SkinTrack technology which enables continuous touch tracking on the skin by using a ring emitting high frequency AC signal, and a sensing wristband with multiple electrodes. They’ve created sensor band and ring prototypes to demonstrate the technology. The ring includes an oscillator that generated a 80Mhz sine wave at 1.2Vpp. It consumes 7mA during operating meaning that they could get 15 hours out of the 100 mAh battery used in the prototype. The wristband features four pair of electrodes coupled with AD8302 RF/IF gain and phase comparator chips in order to derive X and Y coordinates from the phase of the signal. The sensing board produces eight analog values which are sampled by Atmel ATMega328 microcontroller’s 10-bit ADC inputs, and transmitted to the watch using a  Nordic NRF8001 Bluetooth Low Energy (BLE) […]

Tacterion Brings Capacitive Touch to Smart Clothing and Various Materials or Surfaces

With the advance of smartphones and other mobile devices, we’ve all been used to capacitive touch screens, but Tacterion, a German company born out of the Institute of Robotics and Mechatronics, at the German Aerospace Center, has designed “artificial skin” sensors that bring capacitive touch and other features to all sort of materials. Since the company wants to protect its IP they don’t disclosed much details about the inner working of their sensors: The patent protected technology is completely polymer-based. The technological principle are sensitive elements that measure based on transition resistivity: The more pressure is exerted on the polymer-based, electrically conducting elements, the lower the transition resistivity is, which is being measured continuously. Using our highly integrated high-speed readout electronics, a matrix of sensor elements can be combined to form sensitive surfaces. The readout electronics provides information regarding pressure and its distribution at a frame rate of 400 Hz. […]

Alps Electric Smart Mouse Would Let Your Employer Monitor Your Stress Level

Work and life in general can be very stressful, and a Japanese company called Alps Electric wants to enable employers to monitor their staff mental stress level using a mouse that includes a “near-infrared spectroscopic sensor” reporting hemoglobin level, oxygen saturation and pulse, as well as an environmental sensor for temperature, humidity, etc… data. There’s no special way to use the mouse, and the end-user would just control the mouse normally. with all data apparently sent to a centralized system. The mouse  was demonstrated at Medtec Japan 2016, on April 20 to 22 in Tokyo. The sensor development is scheduled to end by Q1 2017, with samples shipping in the spring of 2017. There will certainly be ethical questions raised: Is that a welcome addition to the workplace to help employer better take care of their health, or a step too far and an invasion of privacy?
