A neuromorphic imager based on a cascaded optoelectronic synapse

An optoelectronic device that converts light into a postsynaptic signal after two stages of cascaded potentiation can mimic the synaptic facilitation function of the human retina and could be used to create a curvy neuromorphic imager.

An epicardial bioelectronic patch made from soft rubbery materials and capable of spatiotemporal mapping of electrophysiological activity

An epicardial patch made from materials that match the mechanical softness of heart tissue can perform spatiotemporal mapping of electrophysiological activity, as well as strain and temperature sensing, pacing and ablation therapies, and energy harvesting, while deforming with a beating heart.
