With the popularity of smart devices, the development of wearable medical devices is also on the rise. This type of device is mainly used for real-time monitoring of the patient's physical condition, so it is required that these devices have the highest possible flexibility and electrical conductivity.
Currently, single-walled carbon nanotube applications have covered all types of existing silicone rubber, including liquid silicone rubber, room temperature vulcanized silicone rubber, and high temperature vulcanized silicone rubber, achieving all levels of conductivity needed from antistatic to electromagnetic interference shielding.

Conductive silicon rubber commonly used conductive particles, mainly divided into the following three categories:

(1) Carbon materials: mainly including carbon black, graphite, carbon fiber, carbon nanotubes and graphene, etc.

(2) pure metal particles: gold powder, silver powder, copper powder, nickel powder and aluminum powder, etc.

(3) composite conductive particles: silver plated copper, silver plated nickel, silver plated aluminum, nickel plated graphite, silver plated glass beads.

These conductive particles have the characteristics of good electrical conductivity, easy filling, easy dispersion, aging resistance and moderate cost. If necessary, these conductive particles can be further surface treatment. The conductive properties of conductive silicone rubber prepared by different conductive particles and different filling amounts are different. Therefore, what kind of conductive particles should be selected should be determined according to the conductive properties to be achieved, and two or more conductive particles can be mixed.

Application vision:

One treatment for Parkinson's, which has tremors in the extremities, is to send weak electrical stimulation to the brain to relieve symptoms. The brain can also be stimulated by stimulating the peripheral nerves of the arm with electricity from a silicone rubber device wrapped around the arm, according to the report.

The use of single-walled carbon nanotubes can reduce the negative effects of additives on elastomer properties. Existing additives have some negative effects on elasticity, mechanical properties, coloring and processing. Due to the unique physical structure of SWNTs, such as high aspect ratio and high specific surface area, various properties of the final compounds can be improved.
