Abstract :
This paper presents a low-power wearable biosignal monitoring system. The proposed system can communicate with smartphones using Near Field Communication (NFC) to check vital signs easily at any time. It comprises a battery, electrodes, a triaxial accelerometer IC, an NFC tag IC, and a biosignal processor LSI. The proposed biosignal processor LSI, fabricated using a 130-nm CMOS process, comprises heart rate monitoring circuits, a 32-kbyte ferroelectric random access memory (FeRAM), an accelerometer interface, and an NFC interface. The proposed system consumes 38.1 μA for logging application at 32-kHz operating frequency, with 3.0-V supply voltage.
