Batteries can be made quite small today, and batteries can be recharged wirelessly by magnetic resonance. So feasibly, the battery could be implanted in the temple near the eye and be recharged by putting a charger against the temple. It might also be possible to charge the eye simply with the light that enters it. If the battery is running low, just stare ...

Disclosure: we (Sound Intelligence) sell this exact product. The problem is not detecting a loud noise. That's actually quite easy. But the vast majority of loud noises aren't gunshots. Is your android going to duck every time a door is closed? Another answer quoted 120 dB. That's at the standard measurement distance of 1 meter. Guess what? At that ...

Although I like the classic cyberpunk concept that states that nanomachines build a small turbine generator in one of your biggest veins (like the inferior vena cava), I understand you want something built into the eye... What about an enzymatic generator? It extracts energy from the sugars and fats of your body. You can make it tap into the bloodstream, ...

Go for the simplest solution: millennium bug. You would think that humanity would have learned after Y2K. Nope. In another post I described how GPS has a millennium bug every 19 years or so. This is due to a design flaw, and the fix is people having to buy new GPS devices every 19 years. We are now in the first generation of devices which may survive this ...

Well a concept is a network of associations, the foundation of this network are your sensory inputs (or whatever interpretation your brain receives, a lot of pre-processing occurs in the nervous system) for example icecream is defined by its temperature, appearance, smell, flavour, all the properties that come to mind when you think of the word "icecream". ...

I'm going to propose a different direction: the failure was intended by the original designer. While I wouldn't presume to rewrite the history of your world, this problem does invite some interesting backstory (though you may feel this rips off I,Robot a little too much). Cybernetics, Enhancements, Plugs. Whatever you call them, everyone is using them - ...

Replacing them is (literally) a pain. In real life, you could classify most prosthetics into two types - ones that go inside you (pacemaker, VP shunt), and ones you wear like clothing (hand, foot). In a cyberpunk setting you often also have fictional ones that are partly inside the body, partly outside, and firmly attached to the skin somehow (ouch?) and ...

This is one of those things that sounds cool until you think about it. If our goal is to get as much of her body converted over as possible this is just going to be sad. She now has prosthetic arms and legs. They work but they are poor substitutes for the real thing. Amputees actually have to have multiple prosthetics for different uses. We can replace ...

In todays world the main barrier to direct brain-machine interfaces is that the body rejects implants. Typically the body will grow a barrier/capsule around any foreign object placed into the brain (in order to isolate it). Presumably they have solved this problem in your world. That all changed when the I386 virus came into contact with the first human. ...

Humans routinely learn and master how to control an excavator: a very long arm with the body moving on way more compact base, which is the same situation you are describing. It doesn't take that long to achieve a good coordination with moving the excavator and operating its arm: I would say that a few months of routine usage are enough to become proficient. (...

A month to a year The human mind is incredibly flexible. Via association we can learn a great deal. When you start riding a bike or car you can see this very well. Moving your arms and legs in certain ways creates desired movement. We haven't evolved with these movements, yet we can learn them. Even better is controlling a computer for example. Moving your ...

Here's a clip of a monkey feeding itself with a simple robotic arm controlled via a direct brain interface, taken in the implausible scifi future of 2008: (Nature article on the subject) This work was done by these folks who have since done some work on humans (PDF article). They aren't saying how long it took to train her (or the earlier monkeys), at least ...

The tech is not the issue, card vs chip = no difference There is no security in obfuscation (Image Source, licence CC-BY-NC 2.5) Since cards of all sorts are moving towards contact-less RFID technology anyway, there is little difference between using a chip or a card to authenticate your identity, other than that it is much harder to steal the chip, ...

Change of diet: the implants need some chemicals/proteins/etc. to work, or to be able to interface with your biology. Something wiped out a kind of a crop, that forms the major part of your societys diet, that was the only source of this protein. Or the opposite, some company introduced a new soda, that became such a big hype, that almost everybody tried it. ...

Using such an implant successfully would require a lot of training. When you make a phonecall with a mental command, it becomes hard to differentiate between thinking about calling someone and actually doing it. Using uncommon pictures to control the actions of the implant might not be a good idea either. It is just too easy that mental stimuli from your ...

No. The reason why human athletic levels are where they are have nothing to do with control and everything to do with tolerances. This is actually a similar reason to why being in a car accident or falling off a cliff is so dangerous; the human body is not designed to go at those speeds or 'jump' that high. For one thing, our bones are designed to be strong ...

It would need to be implanted into the brain stem. The brain stem is the "device" that controls all of the messages between the brain and the rest of the body. It also controls basic functions like breathing. So you would simply cut part of the line, re-route it through the device and bam. You might not even have to cut the signal you could just hijack it ...

I think signal convolution between the sound and a prerecorded shot sound should suffice to determinate that is actually a shot (a trained human can easily separate shot from other sounds), and we admit that this computation is instantaneous. Thus, only the sound travel time must be taken into consideration. The speed of sound at sea level and in ISA ...

Radioactive Diamond Batteries Diamond naturally generates electricity when exposed to radioactivity. So, radioactive diamond batteries are made by forming carbon-14 into diamond and encapsulating it in regular non-radioactive diamond. These diamond batteries have a very specific purpose – low power and extremely long life. A standard twenty-gram non-...

Body Heat AND Solar Power This has already been done successfully with this smart watch. For solar power, eyes are open for the majority of the time you are awake and a cybernetic one could charge through light energy as you go about your day. Of course, this would just be a supplement to the main source of energy, body heat. The eye socket is inside the ...

Who cares? No-one reading your story actually cares what the reason is. What we care about is the story you tell about the consequences. The reason is a MacGuffin which doesn't have to exist in any defined way. Think of the classics. You don't need to know how Victor Frankenstein connected up the nerves and blood vessels, only that he did, and this is how ...

Failed to renew the domain name It's just one of the old-fashioned things again. All the implants are cloud-connected, of course. That's how they talk to each other, and smooth the communication between their human hosts. And therefore, they all have the same hostname programmed into them. It would be a real modern Babel otherwise, if your implant could ...

Actually, you'd be better off not building an oxygen storage unit, but to build a reversible glucose-oxygen fuel cell. This would have the advantage that when it was doing its thing, not only would oxygen be supplied and $\text{CO}_2$ removed, but glucose would also be supplied, making the recipient almost completely self-sufficient as long as its power ...

Either remove the tech in question, or even better, lock it down, and use it to further monitor and control the inmates. That tech can be used to educate / brainwash inmates by constantly broadcasting educational programs, or offering them some entertainment as a reward for good behavior. Furthermore, you can probably tap into what they're looking at at ...

Muscle movements In an automatic quartz clock, the wrist movements cause the rotation of a small pinion, which is connected to a small power generator. I think that somebody willing to implant an artificial eye in place of his own one, wouldn't mind having another dozen of small implants in some other places of his body plus a more invasive surgical ...

As I see it, for the effect to be quite sudden and global, there are two options 1) outer influence, new kind of radiation, aliens, gods, magic appearing out of nowhere you name it. Generally not very plausible, but there are stories set in worlds in which such a game-changing event occurred. If the setting is interesting enough, the question how it came to ...

Here's the deal with crime and punishment. Generally speaking while prisoners in some countries retain SOME rights they lose rights in every country while incarcerated and sometimes, depending on the severity of their actions lose rights even after serving their time. Ethics is a matter of social norms. Not right and wrong. You can claim that ethics is ...

Letting steam cool in a sealed container is a good way to make a weak vacuum. It won't do much except make it hard to open the container. You would do better to use a pump to just pressurize the air. That will be mostly immune to cool down. the air will heat up as it is being put under pressure and will cool down some later but not enough to make a ...

As @Erik has already stated, it reduces the chances of complications due to loose hairs during the numerous surgeries required by the CYBORG program, particularly those involving the noggin. It's the same reason they shave patients going in for brain surgery - make's it easier for the surgeons to see what they're doing. As an additional note - maybe some ...

A glucose based fuel cell would be a good fit. The fluid around the brain is full of glucose. The fuel cell and a brain/machine interface circuit would be placed somewhere inside the skull. The fuel cell would use that glucose to generate small amounts of electricity to power both the eye and the interface between the eye and the brain. The eye would ...
