Notch Motion Sensors
Notches are small devices that can form a wireless sensor network of 2 and more nodes. Each module is equipped with 3 high-accuracy MEMS sensors, including an accelerometer, a gyroscope, and a compass. Onboard memory allows to motion capture without a constant smartphone connection. Notches use Bluetooth Low Energy to communicate with the smartphone.
Notch devices have a shape of a truncated triangle also known as a ditrigon. Notches are slightly bigger than a standard SD card, slightly thicker than four stacked US 25 cent coins and are about the same weight as a US dollar coin.
Communication
Notches use BLE (Bluetooth Low-Energy) to communicate with the target smartphone. Notches also form a proprietary, wireless sensor-network to synchronize between devices and for internal communication.
Battery Life
Notches run on rechargeable, Li-Po batteries. It takes about 1 hour to charge your devices under sufficient power (>500mAh). During charging, the notch blinks green - when the battery is close to full, the device shines green. We recommend unplugging the dock after more than 2 hours of charging.
