Track your binky and your baby

Pacifi-i is a smart pacifier that tracks a baby's temperature and location, while providing an easy way to map a child's response to medication over time. Users can set up reminders on an app to re-take a baby's temperature or administer medication, or find a missing binky with a proximity finder.

Available in February, the $38 pacifier will have a battery can operate for one year, thanks to Nordic Semiconductor's low-energy Bluetooth Smart chip, said the company. The Pacifi-i can run for 12-18 weeks on a single charge if the temperature sensor is not constantly engaged.

Monitor your mouth

Impact-monitoring devices have increasingly popped up as knowledge of sports-related brain injuries become more common. Force Impact Technologies' FitGuard has taken a different approach by monitoring from inside the mouth. The mouthguard is equipped with an Analog Devices ADXL377 accelerometer, a MAX21000 3-axis angular rate sensor, a TI CC2541 2.4GHz Bluetooth Low Energy SoC, and a Seoul Semiconductor SFT825N-S RGB LED. Positioning inside the mouth gives sensors closer access to the brain, and LEDs turn on when a particular level of acceleration and impact is reached.

Force Impact hopes to build a database of impacts for a variety of sports in order to better understand what leads to injury. The mouth guards can be customized by a dentist and will be available in September for $100.


Mouthguards can be bought off-the-shelf or customised.

Perfect your pose

It may be easy to follow a set of asanas in a yoga class, but perfecting your pose requires something more. SmartMat is a smart yoga mat built on a conductive grid placed over a piezoresistive layer with 20,000 points. Following a calibration for individual user's height, weight and experience level, the mat will provide feedback when yoga practitioners are out of alignment via a smartphone app.
