Thanks to improvements in sensor technology, wearables are becoming ever smaller, more precise and cheaper. As pedometers, heart rate monitors or calorie counters, they are increasingly moving away from their usual position on the wrist. They are instead becoming direct components of clothing or other intelligent fabrics, as was presented by start-ups such as Clim8 and Xenoma. However, with the help of electric skin, it is not just physical processes which are being monitored. What is more, these products – such as the wearable accelerometer – collect findings from the relative position of the body in the surrounding environment, track changes in movement and, like GPS, can determine where you start and stop running. They also make the user aware if they are sitting in an unhealthy position at the computer.
The intelligent mattresses from the start-up Beddit work on a similar principle. Sensors lie directly in the bed rather than in clothing. They aim to help the user enjoy a healthier sleep. Sleep-tracking is automatic and invisible; it integrates seamlessly into everyday life. Blood sugar levels can also be measured non-invasively. With the wearable K’Track users can check their blood levels without having to prick their finger and receive a warning if their blood sugar is low.
