The Orange Goo That Could Save Your Laptop 285

Barence writes "A British company has patented what can only be described as an orange goo that could save your laptop or iPod after a nasty fall. The amazing material is soft and malleable like putty, but the substance becomes solid instantly after impact. You can punch your fist into a ball of the material sitting on a desk and not feel a thing, according to the staff at PC Pro who have been testing the material, called 3do. It's being used by the military, the US downhill ski team, and motorcycle clothing manufacturers to provide impact protection in the event of a crash. However, it's also appearing in protective cases for laptops and MP3 players."

    Isn't the point of protection to absorb the impact? That's why bubble-wrap is squishy. If this instantly turns solid, wouldn't that mean that the g-forces, the energy of the impact is not absorbed by it and is thus transferred to the item inside?

      Presumably the energy is absorbed by it turning solid. Similar in principle (in vague terms) to how the bonnet of a car (hood to USA people) is designed to crumple so that it absorbs the energy of a crash. Afterwards the bonnet is more condensed - harder - but the energy went into making it so, rather than getting transferred on to the rest of the car and the passengers.

      Well the front of normal cars is designed to do that. SUVs are designed to kill people.

        But its the people in the SUV that will be killed . So be happy.

        Most collisions are single vehicle, involving a car with a fixed object. If we assume that most fixed objects are much more rigid than the vehicle, if you have an engineered crush zone, you'll stand a better chance of survival than if you have a rigid frame.

        My SUV is designed so that it's frame doesn't distort when pulling with a winch. A side effect of that is that it has a rigid frame. Too bad for me, but its a decision I made when selecting it. You may feel free to laugh at me when I hit a tree.

          Not if it hits a cyclist or a pedestrian. I know those are rarer in the USA, but here in Europe, people are driving around in SUVS and when they hit someone on a bike, or an adult or a child - all of which are also more likely to happen in a SUV due to the height - then the chances of that person being killed are much higher than with a normal car.

          Rigid under tension is not the same as rigid under compression. Most SUV's are designed with hardened points for towing (tension) but they still have crush zones for accidents (compression). In fact, because of the size, the crush zones in an SUV are often larger and more effective than those in a smaller car.

          Overall, you are safer in an accident when you are in an SUV than when you are in a smaller car. Of course, this does vary according to the type of accident and overall safety design of the vehicle. You also have to factor in that SUV's are more susceptible to some kinds of accidents than other cars.

      I guess there's a limit to the amount of shock it can absorb. I would imagine its properties have been tweaked so that it stops any impact within its own thickness. Obviously if the impacting object is travelling faster, that results in more rapid deceleration and thus more forces transferred to the delicate internally-bits of your laptop. For dropping off a table though, it probably provides the smallest possible deceleration force against the floor, compared to protection materials currently on the market.

      My suspicion would be that rather than rather than causing the linear deceleration of a simple spring constant, (like most other foams, rubbers, etc.), it provides an exponential deceleration: the stopping force in a shear-thickening fluid is proportional to the speed rather than the displacement. This means that the material starts acting from the very moment of impact, as that is the point with the highest speed. A spring, (or foam, or rubber, or anything else that acts like a spring), would do essentially nothing until the impact has squeezed it enough to get a decent counter-force out of it. But by that time it might be too late, and the spring might have already bottomed out. I'd be interested to see some numbers for this gel, to back up the stuff I've just written!

        Heh, glad I put that disclaimer there. Stopping force is proportional to velocity, (technically shear rate), in a Newtonian fluid such as water or oil: in a shear-thickening fluid viscosity is proportional to velocity. Viscosity is the proportionality constant linking speed and stopping force, so I guess that makes stopping force proportional to the square of the speed.

          Drag in air, water or any other normal substance is always proportional to the square of the velocity. This is because if you double the speed of an object travelling through a fluid, the particles will hit the object twice as fast, causing twice as much change in velocity, and there will be twice as many particles hitting it per second. Combine those two effects and you get the proportionality to v^2.

        Well... we all know what's in this stuff don't we ? It's custard (possibly with some orange food colorant).

        The behavior described here is identical to that exhibited by custard and other liquids with low viscosity but high surface tension. The effect is that low velocity impacts are passed through easily but high velocity impact causes the surface tension to rapidly increase and prevents entry. To put it bluntly, you can run over a swimming pool full of custard, but you can't walk over one (brainiac did an episode on it, though they could have done a better job of explaining the theory about why it works that way - wikipedia is your friend here - as per their usual script, they were mostly interested in the fun-value of a swimming pool full of custard... the test subject did indeed run over it until he got to the middle, was told to stop... and then sank).

        Now I'm sure it's not actually custard in this goo (well, fairly sure) but the phenomenon is certainly not new and has been known for a while. What seems new is that this is a much lower liquidity and viscosity than most of these substances (it appears to be at the level of clay or playdough rather than a flowing liquid) - which clearly makes for a whole new range of practical applications, since it won't soak into things or leak, you can make things like laptop protective cases lined with the stuff which would be impractical with custard....

      A squishy material just softens the impact by slowing the deceleration of your momentum. The problem is if the impact force is high you need a lot of padding to soften the blow. By turning solid on impact you material instantly distributes all this force over a large area i.e. all the force isn't released on e.g. the corner of your laptop causing it to shatter. This is similar to putting a hard cover around your object (like a motorcycle helmet). The advantage of this material is that is is flexible in it's normal state so it can met integrated in clothing etc without limiting movement.

      This video has a great example: http://www.youtube.com/watch?v=JceDaEMIHKE&feature=related [youtube.com]
      They use a cap with the material to protect a watermelon from impact with a hammer. With a normal squishy material you'd need a really thick layer to soften a blow like that and a hard material would restrict movement.

      It's a kind of best of both worlds solution.
    • by LWATCDR (28044)

      My guess is that it will be layered with other material.
      By turning hard it will spread out the impact over a larger area.
      A good example of how can work would be to take two sheets of foam. Hit one with a tack hammer.
      Take a piece of plywood and put it on the other sheet of foam and hit that with a tack hammer.hammer.
      So use a layer of the goo and a layer of foam.

    Impact resistance is complicated, but there's parts that are very, very simple. Let's say you drop your laptop from five feet up. When it hits the ground, it'll be going at a certain velocity (I am currently too lazy to calculate it) with a certain amount of momentum. That velocity and momentum will go into crushing the impact point against the ground. If the impact point is forced to decelerate rapidly, and is a small enough point, it'll be subject to a huge amount of force. Boom, shattered plastic.

    Now we add padding. The thing about padding is that it doesn't actually reduce the velocity or momentum in any way (in fact, unless it's literally weightless, it *increases* momentum.) It also doesn't change the basic physical requirements - that momentum will get absorbed somewhere. Guaranteed.

    There's two ways the padding helps. First, it lets your dropped object decelerate more slowly - instead of having to go from fall to stop in a tiny distance (namely, the amount your laptop plastic deforms without permanent damage) it goes from fall to stop in a much larger distance - the distance that the padding can be compressed. (Plus the plastic deformation.)

    Second, it provides - potentially - a larger impact zone, distributing the force more equally over the plastic of the laptop. A force that would shatter a corner may not do much at all distributed over a few square inches.

    The first part, unfortunately, has some very basic physical limits. If the padding is an eighth of an inch thick, it will provide, at most, an eighth of an inch of extra speed reduction. There is just no way to improve this until you fit your shock absorber with little rockets and sensors to determine when it's about to impact the ground.

    The second part is a lot more theoretically capable, but also a whole lot harder to solve. The ideal situation is a material that somehow deforms at the impact spot in exactly the manner that lets it stop at its maximum deformation point, without any extra jerks or impacts, while simultaneously spreading the impact over the entire surface of the protected item.

    That is a damn hard thing to accomplish. If he's succeeded in it, or in anything remotely like it, I'm impressed.

    The press releases seem to feel that d3o is absolutely fantastic for human garments, where the fabric has to be malleable until the impact occurs. That's quite different from electronics protection, where malleability is simply not an issue, and I'm not convinced that it will make the changeover smoothly.

    We'll see.

    However, this won't protect your precious harddisk. It works very well for protecting humans, mainly because it adapts to the form of the pressing surfaces (aka your head and a wall) and then distributes the pressure over a bigger area. It does almost nothing though for the rate of deceleration - face it, your notebook, falling from the table goes from v^2=2*g*s (s= table height, let's say 0.8m)=4m/s to zero in about - well, let's say 1mm as this stuff gets rigid very quickly. This makes it face a deceleration of 8000g. Hell, let's say 5mm and it's still 1600g. Nope, this won't save your harddisk as they're rated for 300 to 500g in every direction and a lot less when active. Thinking about it, it seems like a good idea for the notebook to come apart on impact, as this might give your harddisk another few millimeters for controlled deceleration and thus keep it withing mechanical specs.
