Porous-Cladding Polydimethylsiloxane Optical Waveguide for Biomedical Pressure Sensing Applications
We report a new concept of a pressure sensor fully made from polydimethylsiloxane with a solid core and porous cladding that operates through (frustrated) total internal reflection. A flexible and sensitive rectangular cross-section waveguide was fabricated via the casting and molding method. The wa...
