  3. What is Bionics? Bionics is: A technology concerned with the application of data about the functioning of biological systems to the solution of engineering problems. (Merriam Webster Medical Dictionary) Or Basically: A technology that attempts to mimic human abilities using machines.

  4. What is a Human Exoskeleton? A Device that: • Is worn by humans • Helps to aid the wearer • Increases Human Performance -Walking or running -Jumping -Etc.

  5. History of Bionics Over a multitude of years, bionics evolved from prosthetics: ________________________________________________________ The first prosthetics: (crude and simple) Ancient cultures -Wooden crutches -Open socket peg legs • Rough on the skin and joints • Didn’t allow for every day function

  6. History of Bionics Over a multitude of years, bionics evolved from prosthetics: ________________________________________________________ The first prosthetics: (crude and simple) The Dark Ages -The first prosthetics crafted from metal • Heavy and awkward • Extremely expensive • Only functioned in battle

  7. History of Bionics Over a multitude of years, bionics evolved from prosthetics: ________________________________________________________ The second prosthetics: (big and bulky) The Renaissance -Iron arms • 1508 (Worn by a German knight) -Iron hands • 1510-1509 (French surgeon) 1. Joints had to be set by hand 2. Released springs to bend the joint

  8. History of Bionics Over a multitude of years, bionics evolved from prosthetics: ________________________________________________________ The third prosthetics: (improved function) • 1600’s-1800’s -Improved legs with ankles and feet -Added tendons (animal intestines) to improve flexion -First non-locking knee joints

  9. History of Bionics Over a multitude of years, bionics evolved from prosthetics: ________________________________________________________ The fourth prosthetics: (lighter than the past) • Civil war - World War II -Switched the steel with aluminum -Used rubber instead of intestines for the tendons -Improved how the prosthetics attached to the body

  10. History of Bionics Over a multitude of years, bionics evolved from prosthetics: ________________________________________________________ The fifth prosthetics: (light and functional) • Present -Made from plastic -Allow for even greater function -Still are a bit awkward to use THUS... BIONICS ARE BORN!!!

  11. History of Bionics Over a multitude of years, bionics evolved from prosthetics: ________________________________________________________ Bionics: (lighter and more sophisticated) • Present Unlike any prosthetic ever created -Use a power source -Work with the applicant -Very intricate

  12. Present forms of bionics Leg: Eye: Ear: Arms:

  13. General explanation of how bionics works • Bionic Leg • Bionic Arms • Bionic Ear • Bionic Eyes __________________________________________________________ Sets of sensors are attached to bionic leg in strategic places -Collect information about 120 time per second -They send information to a microprocessor Microprocessor picks the best walking style -Walking patterns are sent to the motor -Motor drives the bionic leg forward video

  14. General explanation of how bionics works • Bionic Leg • Bionic Arms • Bionic Ear • Bionic Eyes __________________________________________________________ A Series of sensors line a sleeve worn by the patient -detect muscle movements -relay information to microprocessors -microprocessors run the motors -motors move the limb

  15. General explanation of how bionics works • Bionic Leg • Bionic Arms • Bionic Ear • Bionic Eyes __________________________________________________________ -Implanted in the inner ear, through an incision -Sounds are picked up from the external microphone -Sound is converted into an electrical signal via a processor -The signal is sent to the implanted receiver -Electrodes create an impulse stimulating the brain

  16. General explanation of how bionics works • Bionic Leg • Bionic Arms • Bionic Ear • Bionic Eyes __________________________________________________________ -A microchip is implanted near the retina -Images enter the pupil and strike the implant -Photosensor cells convert the image into impulses -The impulses stimulate nerves to send the image to the brain

  17. Leading companies • Victhom- Bionic legs • Otto Bock Health Care- Bionic Legs • The Dobelle Institute- Bionic Eyes • Clarion and Nucleus- Bionic Ear • Liberty Technology- Bionic Arms

  18. History of exoskeletons Humans have been trying to develop exoskeletons for many years: _________________________________________________________ First Stage: (Mainly for protection) • Armoredsuits • Shields • Anything used in battle

  19. History of exoskeletons Humans have been trying to develop exoskeletons for many years: _________________________________________________________ Second Stage: (Focused on human strength) • Hardiman1 Built by General Electric -Lift a refrigerator -Only one arm moved -Too big and bulky

  20. History of exoskeletons Humans have been trying to develop exoskeletons for many years: _________________________________________________________ Third Stage: (Focus on human performance) • 1970 Walking Exoskeleton -Components are still too big -Machine doesn’t work fluently

  21. History of exoskeletons Humans have been trying to develop exoskeletons for many years: _________________________________________________________ Fourth Stage: (Focus on human performance) • Springwalker -Smaller power source -Uses springs instead of wires -Easy to operate

  22. History of exoskeletons Humans have been trying to develop exoskeletons for many years: _________________________________________________________ Fourth Stage: (Focus on human performance) • Bionic Boots • Powerskip • Kangoo jumps -no wires or cables -strap on and go

  23. History of exoskeletons Humans have been trying to develop exoskeletons for many years: _________________________________________________________ Fourth Stage: (Focus on human performance) • BLEEX (Berkeley Lower Extremity Exoskeleton) -Integrates man and Machine -Carry 170lbs easily -Machines moves with the body

  24. History of exoskeletons Humans have been trying to develop exoskeletons for many years: _________________________________________________________ Fifth Stage: (The Future) • Full armor suits for combat • Running/jumping enhancers

  25. Present forms of exoskeletons Springwalker: Powerskip: Bionic Boots: Kangoo-jumps:

  26. General explanation of how they work • Springwalker • Powerskips/Bionic boots • Kangooshoes • BLEEX _______________________________________________________ -User is strapped into the exoskeleton -As you move forward: • Cables are pulled tight around pulleys • The tension wires pull on springs • As you relax, the springs pull back • You are propelled further forward. video

  27. General explanation of how they work • Springwalker • Powerskips/Bionic boots • Kangooshoes • BLEEX _______________________________________________________ Similar to the Springwalker: -Strap the shoes on -When you step a spring is compressed -The spring forces you back up into the air Video

  28. General explanation of how they work • Springwalker • Powerskips/Bionic boots • Kangooshoes • BLEEX _______________________________________________________ Simple jumping shoes: -Place the shoe on your foot -Push down -The band stretches so you are forced upward

  29. General explanation of how they work • Springwalker • Powerskips/Bionic boots • Kangooshoes • BLEEX _______________________________________________________ Exoskeleton is attached to your legs and torso: -More than 40 sensors monitor your movements -Sensors relay information to an onboard computer -The computer adjusts weight distribution Video

  30. Possible Applications Military: • Combat • Missions taking place Where vehicles can’t go Civilian: • Firefighters • Nurses • Recreation

  31. Leading companies • Springwalker- Applied Motion • Powerskip- Powerskip • BOSSBi- Jumping Shoes • Kangoo Jumps- Kangoo Jumps • Berkeley University- BLEEX (Berkeley Lower Extremity exoskeleton)

  32. Impacts (positive expected) • Increased mobility • Increased Performance -Running -Jumping -Strength • Apparatus moves with the body • Expanding markets and newer jobs

  33. Positives (unexpected) • New research in making specialized materials • Entertainment industry is changing: -Exercising -Extreme sports -Etc. • Private companies are creating civilian prototypes

  34. Negative (expected) • Amount of money needed for funding • Specialized parts are required: -Little pervious technology exists -Pieces must be designed and manufactured • Bionics and exoskeletons are extremely expensive! -How does $30,000 sound?

  35. Negative (Unexpected) • Products require motors: -Noisy -Use fuel • Power sources: -Big -Bulky -Need recharging every few hours • Difficult to stand up, if you fall

  36. Recap • Bionics and exoskeletons are fairly new • Aid in human performance • Huge Advancements are taking place as we speak • The line between man and machine is becoming more and more faint
