This is power assist wear of lower limbs.
Recently, a metal frame is used for to an external skeleton with the general power assist wear.
I support lower limbs with soft material such as the cloth with this product.
I explain main structure.
I put a balloon in knee part, back femoral gastrocnemius muscle and support lower limbs by using the tension of the balloon.
This belt is enlarged by real mechanism growing a balloon.
The tension occurs by being enlarged.
I support the movement to lengthen a knee by this tension.
The main target is the elderly person whom muscular strength decreased slightly.
A system to send air to is in this rucksack.
It support lower limbs by sending air from this rucksack.
The control of this system is a contact power sensor in a insole.
I do supply and exhaust of the air by changing an electromagnetic valve with a microcomputer, by sensing this contact sensor.
The future application is movement for maintenance of the standing positions in the factories.
Or movement to start from seat position.
Besides, I research and develop it to use it by the climbing up and down of stairs.
