New Bionic Eye Might See Better Than We Do

Posted by in categories: biotech/medical, cyborgs, nanotechnology, transhumanism

The ability to restore sight to the blind is one of the most profound acts of healing medicine can achieve, in terms of the impact on the affected patient’s life — and one of the most difficult for modern medicine to achieve. We can restore vision in a limited number of scenarios and there are some early bionic eyes on the market that can restore limited vision in very specific scenarios. Researchers may have taken a dramatic step towards changing that in the future, with the results of a new experiment to design a bionic retina.

The research team in question has published a paper in Nature detailing the construction of a hemispherical retina built out of high-density nanowires. The spherical shape of the retina has historically been a major challenge for biomimetic devices.

Researchers Propose New Diamond Nanostructure For Efficient Energy Storage

Posted by in categories: chemistry, computing, cyborgs, nanotechnology, sustainability

One of the biggest challenges for renewable energy research is energy storage. The goal is to find a material with high energy storage capacity and energy storage material with high storage capacity that can also quickly and efficiently discharge a large amount of energy. In an attempt to overcome this hurdle, researchers at the Queensland University of Technology (QUT) have proposed a brand-new carbon nanostructure designed to store energy in mechanical form.

Most portable energy storage devices currently rely on storing energy in chemical form such as batteries, however this proposed new structure, made from a bundle of diamond nanothread (DNT) does not suffer from the same limiting properties as batteries, such as temperature sensitivity, or the potential to leak or explode. I have previously written about carbon nanotubes, and their applications in everything from Batman-like artificial muscle, to an analogy of the fictional element Vibranium, but a lot of research around carbon nanotubes is already focused on energy harvesting and energy storage applications.

What makes this energy storage method different is the method by which energy is stored, and also the related increased robustness of the resultant material. Dr Haifei Zhan and his team at the QUT Centre for material science used computer modelling to propose the structure of these ultra-thin one-dimensional carbon threads. The theory is that these threads should be able to store energy when they are twisted or stretched, similar to the way we store energy in wind-up toys. By turning the key, we force the spring inside into a tight coil. Once the key is released, the coil wishes to release the extra tension held within it and begins to unfurl. In doing so it transfers that mechanical energy into the movement of the toy’s wheels.

A New Bionic Eye Could Give Robots and the Blind 20/20 Vision

Posted by in categories: cyborgs, nanotechnology, robotics/AI, solar power, sustainability, transhumanism

Good news.


In a paper published last week in Nature, though, researchers from Hong Kong University of Science and Technology devised a way to build photosensors directly into a hemispherical artificial retina. This enabled them to create a device that can mimic the wide field of view, responsiveness, and resolution of the human eye.

“The structural mimicry of Gu and colleagues’ artificial eye is certainly impressive, but what makes it truly stand out from previously reported devices is that many of its sensory capabilities compare favorably with those of its natural counterpart,” writes Hongrui Jiang, an engineer at the University of Wisconsin Madison, in a perspective in Nature.

Dynamic Stimulation of Visual Cortex Produces Form Vision in Sighted and Blind Humans

Posted by in categories: biotech/medical, cyborgs, neuroscience

A visual cortical prosthesis (VCP) has long been proposed as a strategy for restoring useful vision to the blind, under the assumption that visual percepts of small spots of light produced with electrical stimulation of visual cortex (phosphenes) will combine into coherent percepts of visual forms, like pixels on a video screen. We tested an alternative strategy in which shapes were traced on the surface of visual cortex by stimulating electrodes in dynamic sequence. In both sighted and blind participants, dynamic stimulation enabled accurate recognition of letter shapes predicted by the brain’s spatial map of the visual world. Forms were presented and recognized rapidly by blind participants, up to 86 forms per minute. These findings demonstrate that a brain prosthetic can produce coherent percepts of visual forms.

This Bionic Eye Is Better Than a Real One, Scientists Say

Posted by in categories: cyborgs, transhumanism

Other researchers who were not involved in the project pointed out that plenty of work still has to be done to eventually be able to connect it to the human visual system, as Scientific American reports.

But some are hopeful.

“I think in about 10 years, we should see some very tangible practical applications of these bionic eyes,” Hongrui Jiang, an electrical engineer at the University of Wisconsin–Madison who was not involved in the research, told Scientific American.
