许多人由于视网膜感光受体的退化而部分或完全丧失视力。由于人体组织对无机材料的排斥，通过植入硅基装置来恢复视力是非常具有挑战性的。我们将探索一种不同的方法，用有机半导体像素来补充受损的视网膜光感受器，这是碳基材料，因此接近人体成分。我们将考虑基于具有不同带隙的三色像素化新型有机半导体制造人工视网膜的可行性。一个原型装置将制造使用精密喷墨印刷有机分子油墨。该项目将涉及有机半导体的光学和电学特性，器件像素/神经接口的模拟以及半导体油墨的高清晰度喷墨打印。

Many people suffer from partial or complete loss of vision due to the degradation of light-sensitive receptors in retina. Restoring vision by implanting silicon based devices is very challenging due the rejection of inorganic materials by human tissues. We will explore a different approach where damaged retina photoreceptors can be supplemented with organic semiconductor pixels, which are carbon-based materials and thus are close to human body composition. We will consider the feasibility of creating an artificial retina based on three-colour pixelated novel organic semiconductors with different bandgaps. A prototype device will be fabricated using precision ink-jet printing of organic molecular inks. The project will involve optical and electrical characterisation of organic semiconductors, simulations of device pixels/neural interface and high definition ink-jet printing of semiconducting inks.
