Design and build an antenna that is optimized for on-body placement. The transceiver must comply with the Bluetooth standard and able to operate at Class 3 power rating (≤ 1 mW). The system should be battery-powered.
The antenna system must be safe and durable, easily reproducible and lightweight. The antenna structure (excluding sensor, transceiver and battery) should be no larger than 30 mm x 30 mm x 5 mm.
Apart from application-specific data, the ArduinoAndroid app must be able to display and log the power received from the system, for comparison of link performance in terms of received power (in dBm).
