Pressure sensors are one of the most widely commercialized ... to the medium under measurement and the other connected to a cavity. When pressure—whether from air, gas, or liquid—is applied ...

These sensors utilize a unique design that includes a circular sealed cavity, allowing them to measure pressure changes accurately by monitoring shifts in resonant frequency due to diaphragm ...

Resonant optical cavities such as Fabry–Perot resonators or whispering-gallery structures are subject to radiation pressure pushing ... resonator by measuring the cavity elastic deformation ...
