The rapid development of point-of-care testing has made prompt diagnosis, monitoring and treatment possible for many patients suffering from chronic respiratory diseases. Currently, the biggest challenge is further optimizing devices to facilitate more functionalities with higher efficiency performance, along specificity toward patient needs. By understanding that diseases may have difficulty breathing within a normal range, respiration sensor developed focusing on sensitivities in lower air pressure range. In contrast simpler airflow data, can provide as an output using magnetic-based sensor. This unconventional but highly reliable approach, combined rest simple 3D-printed design sensor, offers wide range tunability functionalities. Due detachable components device be easily transformed into other uses such inspiratory muscle training or modified cater higher-ranged deep breathing. Therefore, not only does it reach very low measurement (0.1 cmH2O) normal, tidal breathing, also manipulated detect high levels (up 35 cmH2O exhalation 45 inhalation). With its excellent (0.0456 mV/cmH2O inhalation, -0.0940 exhalation), impressive distinction between inhalation exhalation, fully reproducible convenient design, we believe this will pave way developing multimodal multifunctional sensors biomedical field.
