▎ 摘　　要

NOVELTY - The wearable mobile medical assistant system (100) comprises a graphene heart rate sensing system (200), a data transmission system (300) and an alarm system (400). The graphene heart rate sensing system has a multi-layer structure which includes a substrate layer and a pressure sensitive material layer. USE - Wearable mobile medical assistant system. ADVANTAGE - The graphene heart rate sensor has excellent sensitivity and large working range, and has good linear degree in low pressure and high pressure range. DESCRIPTION OF DRAWING(S) - The drawing shows a block diagram of the wearable mobile medical assistant system.
