Description

technical field [0001] The invention relates to a sensor, in particular to a paper-based pressure sensor and a wearable device capable of monitoring respiration. Background technique [0002] As a sophisticated device or device, a sensor can convert various non-electrical signals that are difficult to capture or measure into electrical signals that are easy to detect and display. In particular, flexible wearable sensors have broad application prospects in the fields of artificial intelligence, bioelectronics and medical care, and human-computer interaction. Flexible and wearable sensors with high sensitivity can be used to monitor physiological parameters such as pulse and respiration of the human body, and thus become a hot research direction in the field of healthcare. [0003] For example, the Chinese invention patent with application number 202110307158.3 "Flexible Intelligent Stress Sensor Based on MXene Electronic Fabric Composite Material and Preparation Method" disc...

AI Technical Summary

Problems solved by technology

However, due to the small initial resistance of the sensor, as the applied pressure increases, the resistance of the sensor quickly decreases to the minimum value, thus showing a relatively small detection range

If you want the sensor to show a larger detection range, you need the sensor to have a larger initial resistance, but this will lead to a decrease in the sensitivity of the sensor
