Miniaturized sensors hold up under pressure

Applications as diverse as oil-well drilling and robot-driven surgery are driving demand for improved micro-electromechanical system (MEMS) pressure sensors. As they are made smaller, however, simultaneously achieving high sensor stability and sensitivity becomes progressively more difficult. A research team from Singapore and South Korea has now overcome this technical challenge by producing a miniaturized sensor that couples a key component—a stable diaphragm—with sensitive silicon nanowires.
