Abstract
Proposed is a vibration sensor including: a substrate; a first electrode positioned on the substrate; a support positioned on the first electrode and including a cylindrical hollow hole; and a diaphragm including a thin film positioned on the support and a second electrode positioned on the thin film. According to the present disclosure, it is possible to manufacture a skin-attachable vibration sensor that is attached to a user's neck to detect vibration acceleration in user's neck skin, thus exhibiting a uniform and high sensitivity to a user's voice over the frequency range of the human voice. In addition, the sensor sensitively detects a user's voice through neck skin vibrations rather than through air, thus being free from the influence of external noise or wind, and can recognize the user's voice even in a situation where a user's mouth is covered.
