Black Technology: Too Divine! New Fabrics Can Monitor Human Movement, And Can Also Be Used For Postoperative Recovery.

According to foreign media reports, imagine whether comfortable and cheap wearable fabrics can detect various kinds of pressure and movement.

Now scientists at University of Delaware have created such a technology, which may have some interesting applications.

This material is developed by a team led by associate professor Erik Thostenson and doctoral student Sagar Doshi.

Such as cotton, nylon, polyester or

And so on.

In addition, the adhesion to the surface is low cost.

It is light, pliable and breathable, with a thickness of only 250 to 750 nanometers (about 0.25 to 0.75% of the thickness of paper).

Carbon nanotubes are made up of rolled graphene sheets. Graphene itself is a two-dimensional crystal composed of carbon atoms with only one atom thickness.

They are also conductive, which enables the coating to detect the movement of the wearer's body.

"

It's piezoresistive, because electrical resistivity changes when the fabric is distorted, "explains Thostenson.

This change is measured by continuous low-voltage current passing through the coating.

One possible use of the technology is pressure induction.

It can be used to assess the gait of patients recovering from injury, or to prevent injuries to athletes.

Doshi has tested the material of sole, and found that the pressure data provided by it is similar to the pressure data collected by more expensive force plate device.

In addition, researchers say this

It can also be used to monitor postoperative recovery and to assess pediatric movement disorders when children are at home rather than asking them to go to clinics.
