Abstract :
The wireless body area network (WBAN) includes up to ten sensor nodes and an external control unit to synchronize the wireless power transfer and communication. A battery operated sensor node is designed using discrete components and tested on standard FR4 substrate. The board dimensions are 2.7 × 4.9 cm2 which fits inside the Kinetra neurostimulator casing provided by Medtronic, wherein a six elements array transducer (5 × 10 mm2) is glued. The transponder power consumption is 3.2 mW when transmitting data towards the control unit, and only 49 μW when in sleep mode.
