Ⅰ. The purpose and necessity of research/development
1.1 The purpose of research/development
The most important function of prothesis for the elderly is that of weight-reduction, stability, excellent affinity for skin
○ The purpose of this research is to develop prothesis components using magnesium alloy with the highest strength of metal for lightweight design of prothesis, the small hydraulic cylinder for prothesis to ensure the stability of walking as the first product in Korea and Air Controlling socket liner suitable for sensitive skin of amputees
1.2 The necessity of research/development
By traffic, industrial accidents or vascular disease the number of amputees is increasing continuously. A according to a increasing tendency of the elderly population in Korea, the amputees are increasing in number due to the senile disease ○ The prothesis used by the elderly, unlikely with the general amputees is required as followings;
- light-weightness of the prothesis due to weak muscular strength
- the higher stability of the walk due to low balance of stiffness
- excellent affinity for skin when wearing of socket liner due to vascular disease
○ The socket liner of high quality by rehabilitation engineering research is supplying in Korean market and the foreign country and we need to develop new advanced socket liner with excellent excretion for sweat
Ⅱ. The contents and scope of research/development
○ Development of high-functional and lightweight knee joint for the elderly
- Development of small hydraulic cylinder for prothesis(The first development case for development in Korea)
- Structural analysis for optimization for weight reduction with specific strength of materials
- Development of very lightweight knee joint using the alloy of magnesium
○ Development of foot for the gait of the elderly and ease of life, stability
- Development of structure adjustable the height of heel
- Development of foot with convertible mechanical and hydraulic system

○ Development of Air Controlling socket liner to protect stump of the amputees with senile vascular disease
- Development of open sell type materials for pushing out sweat to protect amputees' feet from getting wet(The worldwide first attempt to develop)
- Development of the forming technology using gel type materials
Ⅲ. The results of research/development
○ Development of small hydraulic cylinder for knee joint
- Development of the modified design, assembly technology, control methods for operating parts in valve of hydraulic system
- Development of shillings mechanism technology with zero Leakage in operating parts
- Development of control technology and the setting method for tension of spring for hydraulic oil having low viscosity
○ Development of ultralight hydraulic knee frame using magnesium alloy
- the optimum structural design considering magnesium alloy
○ Development of ankle device that can adjust the hight of heel
- Development of ankle system with wild adjusting range using hydraulic cylinder
○ Development o Air Controlling socket liner to protect the skin of stump
- Development of open sell type materials for pushing out sweat to protect amputees' skin(The world's first attempt to develop)
- Development of micro void type liner and socket
Ⅳ. Utilization plan of research/development products
○ As a core technology assistive devices for preventing senile vascular disease of the amputees, the functional/lightweight knee joint, foot with the function of height adjustment and Air Controlling socket liner can be utilized in various research for development of protheesis
○ Technology transfer and commercialization
- Commercialization of hydraulic knee joint for the first time in Korea
- Commercialization of foot with the function of height adjustment of heel of Korean amputees
- Commercialization of Air Controlling socket liner to protect skin of stump
