Breathing is the process of exchanging gases between the human body and the surrounding environment. It plays a vital role in maintaining human health, sustaining life, and supporting various bodily functions. Unfortunately, current methods for monitoring respiration are impractical for medical applications because of their high costs and need for bulky equipment. When measuring changes in moisture during respiration, we observed a slow response time for 2D nanomaterial-based resistance measurement methods used in respiration sensors. Through thermal annealing, the crystal structure of MoS is transformed from 1T@2H to 2H, allowing the measurement of respiration at more than 30 cycles per minute and enabling analysis of the response. This study highlights the potential of two-dimensional nanomaterials for the development of low-cost and highly sensitive humidity and respiration sensors for various applications.
呼吸是人体与周围环境之间进行气体交换的过程。它在维持人体健康、维持生命以及支持各种身体功能方面起着至关重要的作用。不幸的是，目前用于监测呼吸的方法由于成本高昂且需要笨重的设备，在医学应用中并不实用。在测量呼吸过程中的湿度变化时，我们观察到用于呼吸传感器的基于二维纳米材料的电阻测量方法响应时间较慢。通过热退火，MoS的晶体结构从1T@2H转变为2H，使得能够以每分钟30多个周期的频率测量呼吸，并能够对响应进行分析。这项研究突出了二维纳米材料在开发用于各种应用的低成本、高灵敏度湿度和呼吸传感器方面的潜力。
