We combine a special hardware component, the Snugfy sensor, with any modern smartphone to create a reliable health monitoring solution. We have developed a smart monitoring algorithm that triggers an alert once the temperature in a footwear or clothing item drops to an unhealthy level.
The data communication solution is built on the newest Bluetooth 4 (BLE) standard. This means we get an absolutely child safe device which is very energy efficient. We have struck a good balance of range to energy efficiency at around 30-40 meters of range with battery life up to a year. The battery is of course easily replaceable.
