| Summary: | 碩士 === 長庚大學 === 電機工程學系 === 102 === Incorrect walking posture and habit usually cause discomfort of feet and even injuries. There are various researches on foot pressure in the patients with amputation who have nerve muscular dystrophy and need assistant equipment , or subjects with muscle unbalance and back pain due to handling heavy items on one shoulder for a long period.
The major causes for the above symptoms are due to the unbalance during walking. The foot pressure from the body weight is focused onto a single point. The non-uniformity support of foot joint usually results in arthritis. Since body weight is pressed on a single point , hardly on the joint area (with only 5 -10 square meter ) during walking or standing. This may cause and finally amputation for people who have nerve atrophy symptom. On the other side, the joint pressure may be increased due to the acceleration and gravity pressure during walking , thereby causing muscle pain.
Recently, most researches on foot pressure are based on sensor or image system , This thesis is to develop a portable system to measure foot force on both foot simultaneously. Five force sensors are put on the points that are the major supporting areas. The measured signals are wireless transmitted to a computer for computing the distribution of foot pressure during inappropriate posture. Our system has an advantage of low cost
and quick setup.
