Abstract :
A wearable MP3 player system on a multi-layered common fabric patch is proposed for an unobtrusive usage in daily life. An inductive coupling transceiver is proposed as a wearable wireless connector in order to eliminate the physical attachment and detachment of the memory card so that enhance the system reliability. It adopts the Pulsed Clock On-Off Keying (PC-OOK) modulation to reduce power consumption below to 185.6μW in total. And Real-time Capacitor Compensation (RCC) scheme compensates for the dynamic variation caused by user´s activities within 3.96μs in worst case. The complete system is implemented on a 2-layer fabric substrate, and the music playback process is fully demonstrated.
