Auto-powered, miniaturized, smart bio-optoelectronic system dedicated to functional contact lenses and real-time wireless biomedical imaging with high spatial and deep resolution

OPTICAL imaging offers a non-invasive, safe and low-cost tool for real-time biomedical health monitoring, supports a broad range of applications toward measuring both the functional and morphological states of the neurovascular system. Using new optical techniques such as functional near-infrared spectroscopy (fNIRS) both the slow-hemodynamics and fast-neuronal signals can be monitored not offered by any other available single imaging techniques. However, to date the realization of this potential to employ these systems in real-time wireless biomedical imaging applications has not been materialized enough with current commercial devices due to the high-power consumption and size issues and their limited low-deep and spatial resolution. The main bulky and power-hungry part of these optical imaging system is usually the light source. The power should be high enough to drive a high-intensity light source and deeply penetrate into the tissue for highly deep resolution imaging. This imposes applying non-portable wired systems or using bulky batteries for only short-term portable operations.
