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.

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
![Page 6: Bionics is: A technology concerned with the application of data about the functioning of biological systems to the solution of engineering problems](https://reader031.vdocument.in/reader031/viewer/2022032722/56649ce45503460f949b0e25/html5/thumbnails/6.jpg)
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
![Page 7: Bionics is: A technology concerned with the application of data about the functioning of biological systems to the solution of engineering problems](https://reader031.vdocument.in/reader031/viewer/2022032722/56649ce45503460f949b0e25/html5/thumbnails/7.jpg)
Over a multitude of years, bionics evolved from prosthetics:
________________________________________________________
The second prosthetics: (big and bulky)The Renaissance
-Iron arms
•1510-1509 (French surgeon)
•1508 (Worn by a German knight) -Iron hands
1. Joints had to be set by hand2. Released springs to bend the joint

-Added tendons (animal intestines) to improve flexion
-First non-locking knee joints
![Page 9: Bionics is: A technology concerned with the application of data about the functioning of biological systems to the solution of engineering problems](https://reader031.vdocument.in/reader031/viewer/2022032722/56649ce45503460f949b0e25/html5/thumbnails/9.jpg)
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

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!!!
