Wireless monitoring system for human small signal detection


●  Target: Wireless human monitoring system
●  Problem: Low sensitivity and efficiency for wireless detection  
●  We proposed the parity-time symmetric resonator circuits for human monitoring system.


●  New principle: the parity-time symmetric resonator circuits
●  Add a negative resistance to the detection circuit only
●  Wireless monitoring of resistance, inductance, and capacitance change 


●  Enables wireless measurement of weak human signals.
●  Sensor side: no power supply required, cost reduction possible
●  Detector side: only add negative resistance


● Wireless biosensor for health monitoring
● Example: Smart contact lens for glaucoma and diabetes detection
● Implantable medical devices for wireless sensing and therapy
