Power Armor For the Elderly 279

Posted by Zonk from the super-monkey-rocket-old-lady-force-go dept.
aicrules writes "The question of how to care for the growing number of people in the upper age bracket has a new answer - assistive power armor for the elderly." From the article: "The sleek, high-tech get-up looks like a white suit of armor. It straps onto a person's arms, legs and back and is equipped with a computer, motors and sensors that detect electric nerve signals transmitted from the brain when a person tries to move his limbs. When the sensors detect the nerve signals, the computer starts up the relevant motors to assist the person's motions. Sankai says the suit, dubbed 'Hybrid Assistive Limb (HAL) 5,' can let a person who can barely do an 176-pound leg press handle 397 pounds."

      It doesn't have to. You could dial in as much resistance as you want. Consistency is important to frail people, and often fear of injury dissuades them from any exercise at all. This would help.
      • Right... I was thinking about it as controlled dial-in resistance as well. I can imagine that you can use it to work out with as well. Dial in resistance, and do arm curls against the exoskeleton. Same with the legs in a seated position; just switch into workout mode and have an incremental resistance program that is always with you.

The people actually doing the weights increased strength by 30% or so (IIRC), and the people imagining it increased by 20%, with no effect for the controls. Apparently it stengthens the nerve pathways that control the muscle, thereby allowing stronger signals to get through. So, there ya go, imagination can make you stronger! :D

        If you use your own muscles' tension to create resistance to a given motion, as in say a military press, you can build strength in the same muscle groups as with the traditional, weighted equivalent, but in my experience it's wasted effort compared to just lifting heavy weights with low repetitions, or the more difficult bodyweight exercises like one-armed pushups and one-legged squats.

        These latter two types of strength exercises are more efficient strength builders than pure tension exercises like the one

        Individual armour has also been discarded precisely because of weight considerations: you _could_ make a breastplate that could stop a rifle round, but it was impractically heavy.


        This story and video [armytimes.com] show that American soldiers are currently using body armour that can stop rifle rounds. Although it doesn't say so anywhere, the sniper rifle was almost certainly 7.62mm. Here are some pictures of the aftermath: image 1 [msn.com] image 2 [msn.com].


        You are correct however that the armour is pretty heavy, but that is less of an issue for vehicle based soldiers rather than pure infantry.


        However, the problem with this powered exo-skeleton is that just the act of adding more weight, even if it is "self supporting", makes the soldier slower and less mobile (because of extra inertia). They need to be able to react very quickly and be able to dive to the ground, and jump behind cover, etc. There is a very long way to go before projects like this would actually improve a soldiers chances of survival. A better short term prospect is to continue to improve body armour to make it lighter.

        • However, the problem with this powered exo-skeleton is that just the act of adding more weight, even if it is "self supporting", makes the soldier slower and less mobile (because of extra inertia).

          Newton's Second Law states that F = ma - that is, the applied force and resultant acceleration are proportional. Increase the mass, and increase the force, and the acceleration remains the same.

            But the assumption here, (and I'm not a physicist or engineer) is that there has to be minimal lag between the soldier's reactions and the reaction time of the exoskeleton in order to realistically move as quickly as one would without the armor. So in order for there to be no drop-off in reaction time, th

          For example, before and after a collision or some other change in force the momentum of the body is conserved. m1v1 = m2v2 (assuming fully elastic; m = mass, v = velocity). If the soldier is running and suddenly needs to stop, he will have a lot of inertia. Diving to the ground might break his back. Changing direction while mid-stride would also pose a challenge.

    You have to realize though that the Japanese are desperate. While we have plenty of able bodied people to care for elderly, they aren't so lucky. In a matter of decades their work force is going to implode under the strain of an older population.

    I can see this as fallout (no pun intended) from WWII really. The US had a baby boom; Japan had to cope with assimilating, through occupation, a new culture. A culture that was somewhat incompatible with their social norms. Now birth rates are falling because what is left of their old culture in their personalities and sensibilities is grinding against their new culture's pace and density. Raising a family is "lame", so nobody is doing it. All this, of course, is gross over-generalization; take it with a giant grain of salt.
