Functional requirements analysis and design of wearable multi-channel sensing system

Abstract

In recent years, a large number of wearable devices have emerged; and users have higher and higher functional requirements for wearable devices. However, the realization of complex functions of wearable devices often depends on the real-time acquisition of multi-channel sensing signals. Taking the wearable 8-channel PVDF sensor system as an example; this paper studies the functional requirements of this kind of system. It is found that the flexible ultra-thin and long endurance time are two obvious characteristics of this kind of equipment. The key technical problems of the system are completed, such as the selection of MCU, the coding design of multi-channel sensing data, the transmission mode design of multi-channel sensing data and the low power consumption design of the system. A practical design scheme of reliable wearable multi-channel sensor system is designed. This scheme also provides a reliable reference for the design and development of wearable multi-channel sensor system.
