Problems solved by technology

However, the rigid accelerometer currently used monitors the curvature of the cervical spine during the movement of the human body, and the cumulative error is relatively large. It is ineffective for sedentary people, and its wearing method does not meet the needs of the public, causing inconvenience to users' work and life.
However, multi-sensor fusion has higher requirements for data acquisition and processing, and consumes more power.

Abstract

The invention discloses a wearable flexible strain intelligent sensing system for cervical vertebra bending monitoring. The system comprises a flexible strain sensor capable of measuring bending, a data acquisition and transmission integrated circuit with an STM32 microcontroller as a core, and a control interface for receiving signals and displaying output. The flexible strain sensor is woven into a fabric or sticker type and is tightly attached to the skin of the cervical vertebra part, accurate bending data are measured and then input into the circuit, a measuring module of the circuit receives the signals and filters and amplifies the signals, the signals are processed by the microcontroller and then input into a terminal through a wired or wireless transmission technology, a cervical vertebra bending curve is displayed on a terminal interface, and historical records are stored for user reference.

Description

technical field [0001] The invention belongs to the technical field of wearable health monitoring, and in particular relates to a wearable flexible strain intelligent sensor system for cervical curvature monitoring. Background technique [0002] Cervical spondylosis and its complications currently present a large proportion of the affected population, difficult to cure after onset, and numerous and complicated complications. Cervical spondylosis focuses on prevention rather than treatment. Therefore, human cervical spine health monitoring and early mild pain relief have become become an urgent problem to be solved. In recent years, the rapid progress in communication technology, low-power electronics technology, micro-nano processing technology and digital health has continuously promoted the iterative update of wearable devices. In order to promote the development of this novel field, it is necessary and urgent to develop flexible devices that can adapt to deformation and ...
