In the quiet convergence of light and sound, a Norwegian microphone company and an Irish manufacturing specialist have joined forces to solve one of photonics' oldest frustrations: how to assemble precision optical components at the speed and cost that mass markets demand. sensiBel's optical MEMS microphones — which measure sound by tracking the movement of a diaphragm in femtometers of light — have long held promise, but promise requires infrastructure. By adopting X-Celeprint's Micro-Transfer Printing process, sensiBel has found the manufacturing bridge between a remarkable sensor and the wo
