## 5 Conclusions  
The IJP sensor was able to measure the RR accurately at the five postures (standing, sitting at 90\({}^{\circ}\), Flower's position at 45\({}^{\circ}\), supine and right lateral recumbent), with good repeatability which makes it user-friendly, and very convenient for clinical practices with minimal user efforts and training needs. This IJP sensor is promising for continuous RR monitoring in different clinical and daily situations.
