What we breathe out becomes fuel for forests. But inside our own bodies, CO₂ has a secret life. It sparks chemical reactions, shapes metabolism, and may even act as a signaling molecule—and a new tool ...
Sensors are devices that detect and quantify physical aspects of the world around us. The measurement can either be read directly or converted to a signal for processing by electrical, hydraulic or ...
Abstract: In this study, we fabricated a limiting current-type microelectromechanical system (MEMS) sensor and evaluated its sensing performance of oxygen and humidity concentration. The MEMS oxygen ...
