A biomimetic eye with a hemispherical perovskite nanowire array retina

Abstract

Human eyes possess exceptional image-sensing characteristics such as an extremely wide field of view, high resolution and sensitivity with low aberration1. Biomimetic eyes with such characteristics are highly desirable, especially in robotics and visual prostheses. However, the spherical shape and the retina of the biological eye pose an enormous fabrication challenge for biomimetic devices2,3. Here we present an electrochemical eye with a hemispherical retina made of a high-density array of nanowires mimicking the photoreceptors on a human retina. The device design has a high degree of structural similarity to a human eye with the potential to achieve high imaging resolution when individual nanowires are electrically addressed. Additionally, we demonstrate the image-sensing function of our biomimetic device by reconstructing the optical patterns projected onto the device. This work may lead to biomimetic photosensing devices that could find use in a wide spectrum of technological applications.

Коту Фетишисту исполнился год. По этой причине он ходит в шапочке из бюстгалтера.
Дамы, в честь светлого праздника, присылайте фетишисту свои откровенные фотографии. Коту тоже покажу.

Так вот почему котики такие милые

Я проебался поздравить с днем вышиванки, поэтому пощу моррисона просто и безыдейно. Ну посмотрите какой он лапочка!
