Battery-Free and Noninvasive Estimation of Food pH and CO<sub>2</sub> Concentration for Food Monitoring Based on Pressure Measurement
In this paper, we developed a battery-free system that can be used to estimate food pH level and carbon dioxide (CO<sub>2</sub>) concentration in a food package from headspace pressure measurement. While being stored, food quality degrades gradually as a function of time and storage cond...
