Fukui univ : Easy to move in a mid-waisted position! : Pressure distribution sensor
-Electric chairs for agricultural work are interesting-
University of Fukui:
The research group has developed an “electric mobile chair that helps people move in a mid-waist position during farm work.”
A cloth pressure distribution sensor is placed on the seat surface.
Detects the movement of the center of gravity of the buttocks and moves left and right.
In house cultivation, we assume assistance such as crouching and harvesting.
It was confirmed that the load on the leg muscles that kick the ground to the left and right can be suppressed by electric assistance.
Cloth pressure distribution sensor:
We have developed a “pressure distribution sensor made of cloth that combines conductive threads and conductive non-woven fabric”.
Conductive yarn of warp and conductive non-woven fabric,
When layered with the conductive thread of the weft,
A pressure distribution sensor with a mesh structure can be created.
Mesh structure discrimination sensor:
When you put your weight on your butt,
The conductive non-woven fabric is crushed,
The conduction path increases and the resistance value changes.
This position is determined by the mesh structure of the warp and weft threads.
You can make it cheaply because you can use commercially available materials.
Machine learning left and right and front and back:
The cloth pressure distribution sensor can measure the change in the center of gravity in the front-back direction.
Machine learning separates left-right movement and front-back work.
Try to capture the worker’s intentions.
