As respiratory diseases surge worldwide, the limitations of conventional spirometry and bulky pneumography—low patient compliance, signal distortion from motion, humidity or temperature swings—become ever more pronounced. Now, a cross-campus team led by Prof. Hailin Cong (Shandong University of Technology), Prof. Jun Yang (Beijing Forestry University) and Prof. Changyou Shao (Dalian Polytechnic University) has unveiled a high-fidelity, eco-responsible solution in Nano-Micro Letters : a cellulose-based piezoresistive sensor (CPS) that pairs MXene nanosheets with TEMPO-oxidised cellulose nanofibrils inside a customizable cylindrical micro-dome architecture, delivering interference-free, real-time respiration-rate tracking even under bending, high humidity (50–100 % RH) or 30–80 °C thermal fluctuations.
