A monitoring headband which can measure electrocardiogram（ ECG）

electroencephalogram（ EEG）

photoplethysmography（ PPG）

body temperature and human posture is designed to monitor multiple vital signs of the soldiers in battlefield environment. Ultra-low-power consumption microcontroller MSP430 is used as main controller chip

low-power consumption ADS1292 R is used as main collection chip for ECG and EEG

a reflex optical-to-frequency converter is used for collection of PPG

a medical negative temperature coefficient（ NTC）resistor is used as body temperature sensor

digital 3-axis accelerometer MMA7660 is used as attitude measurement sensor. Collected information is transmitted to personal digital assistant（ PDA） through Bluetooth
