- Biocompatible silicone electrodes enhanced with graphene nanotubes exhibit unmached skin comfort and outstanding body adhesion, resulting in high-quality signal acquisition.
- These electrodes comply with safety standards, demonstrating non-marking performance, which makes them ideal for use in healthcare devices and wearable electronics.
The advanced performance of silicone electrodes—characterized by stable electrical conductivity, exceptional flexibility, strong adhesion, and non-marking properties—is made possible by graphene nanotubes. This unique combination of features is essential for medical diagnostics, muscle stimulation, therapeutic applications, and consumer devices such as earbuds and smartwatches. Silicone electrodes with graphene nanotubes ensure optimal functionality by maintaining close contact with the skin, for days at a time. They prevent irritation and allergic reactions and remain securely adhered, even in conditions involving sweat and movement.
Graphene nanotubes, also known as single wall carbon nanotubes, are considered a replacement for traditional conductive agents, such as carbon black and various metal fillers, that often compromise the adhesive and elastic properties of silicone. Their high required loading can affect processing, purity, and cost while posing risks like potential skin contamination.
In contrast to traditional agents, graphene nanotubes with their unique morphology enable electrical resistivity below 10 ohms at an ultralow dosage of less than 1 wt.%. This allows the silicone to retain its original softness and flexibility. The nanotubes form a dispersed, uniform 3D conductive network within the material, preventing surface migration and ensuring reliable performance throughout the electrode’s service life.
These advanced electrodes comply with the RoHS regulation, eliminating the skin irritation and poor adhesion associated with traditional additives. Their superior comfort, improved impedance, and minimal signal interference make them ideal for both healthcare applications and consumer wearables where non-marking and skin-soft properties are crucial.
