Sport Wristband Device by Polar

For the POLAR use case a design was defined, consisting of different modules in a bracelet which are connected and work together as a monitor. Beside different modules the outer sides show Solar Cells (SC) and a display (MLCD) while the inner sides show Haptic elements (HAP1/2) for communication by vibration and PPG measurement interfaces (OHR). All electronics (including MCU, memory, RF transceiver and battery) are assembled on Flexible Printed Circuit. Other technologies are possible to use also like printed electronics or textile wires for interconnections.
