Monolithic integration of light sources and detectors allow for flexible, miniature, low-cost biosensors. We develop GaAs-based Vertical Cavity Surface Emitting Lasers (VCSELs) and PIN photodiodes on a single substrate as a miniature readout module for optical biosensing. These biosensors can be optimized for several sensing modalities including fluorescence, back-scattering and index-of-refraction sensing.

Poor balance, mobility restrictions, fear of falling and fall injuries are serious problems in the elderly and in individuals with various disorders and diseases, including stroke, vestibular pathology, neurological diseases, and musculoskeletal disorders. To prevent falls and evaluate associated outcomes, effective methods are required to appropriately assess balance impairments and optimize therapy. We aim to
