由于视网膜中光敏感受器的退化，许多人遭受部分或完全失明的痛苦。由于人体组织对无机材料的排斥，通过植入硅基设备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，在这种方法中，受损的视网膜光感受器可以用有机半导体像素补充，有机半导体像素是碳基材料，因此接近人体组成。我们将考虑以具有不同带隙的三色像素化新型有机半导体为基础制造人工视网膜的可行性。将使用有机分子油墨的精密喷墨打印来制造原型装置。该项目将涉及有机半导体的光学和电学特性、设备像素/神经接口的模拟以及半导体墨水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.
