Abstract: A bio-inspired imaging device mimicking visual adaptation of human vision in imaging an image employs a neuromorphic vision sensor realized with phototransistors each being a field-effect transistor, a channel layer of which is an atomically-thin layer of two-dimensional semiconductor material. The channel layer is intentionally formed with defects trap states for trapping a portion of charge carriers generated by a light beam incident on the phototransistor such that intensity information of the light beam is memorized. A gate-source voltage directs the defects trap states to de-trap the trapped portion of charge carriers or to further trap an additional portion of charge carriers, allowing the phototransistors to exhibit a time-dependent excitation or inhibition effect on drain current to thereby enable the imaging device to mimic scotopic or photopic adaptation in imaging the image. The gate-source voltage is determined according to a background light intensity used in forming the image.

Abstract: Disclosed herein are compositions of biodegradable scaffolds combined with mesenchymal stem cells and methods of use thereof for the regeneration of cranial sutures and treatment of craniosynostosis, which can help reverse increased intracranial pressure and skull and neurocognitive abnormalities.
