monitoring biological parameters in bioreactor environments, we placed oxygenand pH-sensitive adhesive patches inside a bioflask to monitor conditions during an E. coli fermentation reaction. Bioreactors are closed-environment systems where the cells are cultured under specific conditions to synthesize the final product. Such systems require constant monitoring of DO and pH to optimize the biop...

Optical microfiber-based temperature sensors have been proposed for many applications in a variety of industrial uses, including biomedical, geological, automotive, and defense applications. This increasing demand for these micrometric devices is attributed to their large dynamic range, high sensitivity, fast-response, compactness and robustness. Additionally, they can perform in-situ measureme...

This paper describes the development of a device that combines the electropalatographic measurement of tongue-palate contact with optical distance sensing to measure the mid-sagittal contour of the tongue and the position of the lips. The device consists of a thin acrylic pseudopalate that contains both contact sensors and optical reflective sensors. Application areas are, for example, experime...
