The hardware design of Totem Pop is based on designs of partner company Totem Open Health, that released their initial run of health trackers for developers in October, 2015. The small tracker has built-in motion and temperature sensors and can be easily extended with external analog sensors. This comes in handy in for example measurement of bending, pressure or humidity, sensors that aren’t integrated in most wearables.
Raw data can be saved locally on an SD-card with a frequency up to 1000 times per second, data can also be shared wirelessly to the mobile app using Bluetooth Low Energy.The built-in battery is rechargeable over USB and lasts up to 10 days. Due to it’s modular design, the wearable can be worn on different places on the body.
