A kind of multifunctional passive electronic skin system and preparation method thereof

Abstract

The invention discloses a multifunctional wireless passive physiological health monitoring device, which includes a piezoelectric / thermoelectric blood pressure monitoring module, a thermocouple / thermoelectric body temperature measurement unit, an electrophysiological potential measurement module based on surface electrodes, and the like. The current modules use the principles of blood pressure flow, body temperature changes, and electrophysiological potential differences in biological tissues to directly convert blood pressure, temperature, and electrophysiological potential into voltage signals without an external power supply. The designed multifunctional wireless passive physiological health monitoring device has a certain stretching and deformation ability, actively adapts to the soft skin surface, and records the physiological health information of the human body (body temperature, blood pressure, electrocardiogram, electromyography, etc.) in real time. The invention also provides a method for processing and preparing a multifunctional wireless passive physiological health monitoring device, which has the characteristics of softness, light weight, long-term and stable recording of human physiological information, does not affect the daily behavior of the human body, and improves the comfort of the device and portability.
