The evolution of contact lens technology is rapidly transforming these simple vision-correcting devices into advanced, multifunctional platforms. By embedding innovative sensor technologies onto contact lenses, it becomes possible to continuously monitor a person’s own well-being in a comfortable and non-invasive way. In this work, we explore the possibility of creating a multifunctional smart contact lens sensing platform that can one day help people easily track important health information, offering new ways to stay connected with their bodies without interrupting daily life.

Black Phosphorus (bP) is a highly promising host material for future optoelectronic devices operating in the mid-wavelength infra-red (MWIR) regime of 3-5 um. bP is the most stable allotrope of phosphorous with a bulk direct bandgap of 0.3 eV that is highly tunable by alloying, applying strain, and varying the thickness, and with many remarkable electronic and optical properties ranging from low surface recombination velocity to high carrier mobility. Both MWIR LEDs and photodetectors based on mechanically exfoliated bP flakes operating at room temperature have shown superior...

Multispectral and hyperspectral imaging are important optical inspection technologies. They collect the spatial and spectral information of the incidental light into 3D hypercubes, which can be post-processed into material and structural mapping of the scene. However, acquiring and analyzing the 3D hypercubes set great challenges in data collection, transportation, storage, and computation. The much higher energy, bandwidth, and memory budgets limit the implementation of high-speed, high-resolution hyperspectral imaging to achieve intelligent machine vision. This project introduces an...
