artificial limb Jack Altmire by Jack Altmire https://padlet.com/jaltmire22/1uze0nr0fmcm en-us 2017-01-29 16:33:19 UTC 2017-02-01 01:24:30 UTC hello@padlet.com 1 SENSE of FEEL jaltmire22 https://padlet.com/jaltmire22/1uze0nr0fmcm/wish/150098985  1.  John Sabolich's "Sense of Feel" system.  Sensors, implanted in the ball and heel of an artificial foot, are linked to an electronic unit that sends signals to the amputee's nerve endings through electrodes. The "tingly sensation" that the nerves receive are then passed to the brain as if it were received from a real leg.

2.  greater sense of balance and mobility

4.  can control speed, "If you walk fast, it walks fast. - makes it so athletes can perform more realistically and parents can even play with their kids (soccer)

5." the sense of touch has much more to do with what is going on in our heads than at our fingertips, " because even though the limb isn't officially there, the brain doesn't realize it all the time ]]> 2017-01-29 16:33:58 UTC https://padlet.com/jaltmire22/1uze0nr0fmcm/wish/150098985 2 SPORTS (ARMS) jaltmire22 https://padlet.com/jaltmire22/1uze0nr0fmcm/wish/150099032 1. Now Mac can even swim in his waterproof limb.

2. there was an arm wrestling match between an amputee and a man with all of his limbs

3. special prosthetics that help double-amputee parachutists who jump successfully]]> 2017-01-29 16:34:40 UTC https://padlet.com/jaltmire22/1uze0nr0fmcm/wish/150099032 3 MATERIALS USED jaltmire22 https://padlet.com/jaltmire22/1uze0nr0fmcm/wish/150099036
2. polyethylene and carbon fiber frames make prosthetics much lighter

5. high-tech titanium and carbon fiber, looked a little like curved skis with thick rubber soles of running shoes glued to the bottoms

7.  Today, suction holds most limbs in place and space-age materials, including acrylic resins, carbon fibers, thermoplastics and titanium alloys, make limbs stronger and lighter.

8. Most artificial arms are controlled by a cable that loops around the opposite shoulder. Movements of that shoulder produce movement in the arm prosthesis. Artificial legs are mostly controlled by the body's normal walking movements.]]> 2017-01-29 16:34:43 UTC https://padlet.com/jaltmire22/1uze0nr0fmcm/wish/150099036 4 PHANTOM LIMB jaltmire22 https://padlet.com/jaltmire22/1uze0nr0fmcm/wish/150099039 1.  some amputees experience lingering pain from lost limbs

2.  Army Sgt. Nicholas Paupore is using a large mirror to help adjust to the loss of his leg after suffering injuries in an explosion.
The mirror reflects the left leg so his brain thinks it is showing his right leg- the one that was destroyed while on duty in Iraq. This helps with a phenomenon, called "phantom limb¨

3 Amputees can feel missing hands

2. 1950- prosthetic legs made of wood with a belt that came up over shoulder, weighed 27 pounds. Today-  2 pounds- polyethylene socket, carbon fiber frame, and a foot formed with urethane rubber

1.After WWII in the 1970´s, prosthetics stronger and lighter due to carbon fibers and composites ]]> 2017-01-29 16:34:59 UTC https://padlet.com/jaltmire22/1uze0nr0fmcm/wish/150099054 7 MICROCHIPS jaltmire22 https://padlet.com/jaltmire22/1uze0nr0fmcm/wish/150099060 4.     "The goal of these systems is to be completely seamless and natural, like your own limb," Herr said. If the artificial limbs are as natural as possible, the people will be more likely to use it and get back their regular lives as much as they can.

3. Judy Shorter- prosthesis with a microprocessor in her knee that controls the swing phase of her left leg. It holds memory of her steps at different speeds so that her artificial leg will move at the same speed as her natural one.

translates a personś thoughts to computer commands, a quadriplegic can switch on lights and move a computer cursor with thought alone.

6. a microchip about the size of a grain of rice, into existing leg muscle where it can pick up signals from nerves and send movement instructions to the prosthesis. Sensors on the heel and foot of the prosthesis relay information back to the microprocessor to guide movement. ]]> 2017-01-29 16:35:03 UTC https://padlet.com/jaltmire22/1uze0nr0fmcm/wish/150099060 8. 3D PRINTING jaltmire22 https://padlet.com/jaltmire22/1uze0nr0fmcm/wish/150099062 1. Faith, a 7 year old girl, was able to design and 3D print a prosthetic hand
created in less than a day, is easy to use, and cost a total of $50 to create. Weighing only a pound, the tool is made of the same materials used in drones and automobile parts.

2. teen- lost arm because his country (Sudan) was in war- 3D printed arm -allowing Daniel to feed himself for the first time in two years

3.  created a 3D printing system for super-lightweight, stylish prosthetic legs. The jet black design is made from titanium powder or high-strength plastic,]]> 2017-01-29 16:35:06 UTC https://padlet.com/jaltmire22/1uze0nr0fmcm/wish/150099062 9 CHILDREN jaltmire22 https://padlet.com/jaltmire22/1uze0nr0fmcm/wish/150099066  1. a piano student who had lost half his forearm. The young man wanted to continue his music studies so they made him a prosthesis with prongs that sloped downward the way a pianist's fingers do as they hover above a keyboard, and tips that did not ping when they struck the keys, They could spread out to cover one octave. 

2. children who have lost limbs because of cancer are bonding with animals that have artificial limbs, too

3. animals, like a horse named Molly, are visiting schools and other places to give people hope for all the possibilities that can still happen, even after tragedy

2 hope to be more (smart)- use brain waves more

3 going to put a flash drive in the fingers

4. biohybrid limbs that combine bone, muscles, and nerves with artificial parts

2. Oscar Pistorius- amputee competed in olympics, not just paralympics even though he has artificial legs
5. Adrianne Haslet-Davis- ballroom dancer]]> 2017-01-29 16:35:15 UTC https://padlet.com/jaltmire22/1uze0nr0fmcm/wish/150099078 12 SPORTS (LEGS) jaltmire22 https://padlet.com/jaltmire22/1uze0nr0fmcm/wish/150107135 1. Greg Mannino, able to continue active lifestyle with comfortable leg prosthesis- skiing - device holds energy and torque so the ankle and foot can bend more naturally- "if you break it, well, there's no surgery--you just fix it."

2. His foot prosthesis allows him to run and to play softball, and when he wears slacks it's not noticeable.

3. Oscar Pistorius- South African runner, whose legs were amputated when he was a baby-uses prosthetic running legs called Cheetah blades. He won three gold medals in the regular Olympics

4. Reggie Showers- motorcycle drag racer who has a prosthetic leg wins races ]]> 2017-01-29 18:24:53 UTC https://padlet.com/jaltmire22/1uze0nr0fmcm/wish/150107135 6 SOLDIERS jaltmire22 https://padlet.com/jaltmire22/1uze0nr0fmcm/wish/150113228 1. help veteran amputees regain their skills- some even return to active duty
