Breath sensor characterization in patients diseases-controlled condition / Norfatiha Suhimi

During human breathing, the inhalation and exhalation processes are involved. Most research in human breath analysis focuses on both the bulk matrix and breathing pattern. The conventional way of diagnosing the diseases usually took longer time with painful procedures. Different types of diseases ca...

Research shows that the sensor can operate indoors and outdoors within 1.5 seconds of response time. This indicates that the breath sensor can capture human breathing. Furthermore, the sensor's sensitivity exceeds the baseline reference of 10mV, so it is sensitive enough to detect moisture in human breath regardless of the conditions under which it operates. 16 healthy diabetic patients were involved in this study, while 6 unhealthy diabetic patients were included.
