Get Your Biometrics On #WearableWednesday

Lewe Wristband

It looks like a child’s watch, but this open source wearable, named LEWE,  measures biometrics according to Bits and Pieces from the Embedded Design World. This Arduino wristband looks bulky now, but it’s merely to facilitate explaining construction.

According to Boris Landoni of OpenElectronics, the goal of Project LEWE is to leverage available tech and create a low cost platform using sensors for data collection.

“[Ultimately, everything can be] integrated into a single board or two, in a more compact fashion that can be worn thanks to a special container with a wristband.”

The current iteration of the LEWE prototype currently supports at least five functions, including:

  • Measuring body temperature and sweat rate
  • Local display of recorded data
  • Relaying information to a smartphone app
  • Sending and storing data to the cloud
  • Organizing data in graph form for analysis

Lewe Build

This wristband uses a variety of shields, which are rectangular, and also uses a digital readout. It would be very interesting to see a circular version that gives biometrics through visuals, rather than numerically. This could be done with a FLORA and a Neopixel Ring, similar to the FLORA NeoGeo Watch. A temperature sensor could be incorporated that would take a reading and send the results in the form of color, or amount of Neopixels lit on the ring. A heart rate sensor could also be used with results blinking the Neopixels. Sending information is definitely the tricky hurdle. Since most shields are bulky, it may be wise to figure out a method such as an SMS module, so information could be sent as a text message to a device. Whether you attempt to do this using a traditional Arduino, or create your own version, this is definitely an exciting challenge.
