Healthcare devices like wearable electronics, body sensors, bionic prostheses, and massage tools rely on key features: electrical conductivity, elasticity, and softness. These devices must deliver accurate data and signals to and from the human body without causing discomfort and irritation or leaving marks on the skin.
Graphene nanotubes ensure RoHS compliance, provide precise conductivity for accurate sensor measurements, and maintain flexibility and softness — all without compromising skin comfort and device durability.
Thanks to the unique morphology and characteristics of graphene nanotubes, they provide stable conductive properties to silicone. The granted electrical conductivity enables the precise delivery of electronic impulses to and from the human body, ensuring accurate diagnostics and effective treatment without causing skin contamination.
Ultralow working dosages — dozens of times lower than those of other conductive additives — preserve the final product’s softness and color while maintaining standard processing conditions without generating carbon dust or drastically increasing viscosity.
Do you have questions or ideas for new applications of graphene nanotubes?
Graphene nanotubes form an effective 3D network throughout on-skin sensors, making them electrically conductive and able to receive bioelectrical signals through transmission of electrical currents from the human body, while preserving the original silicone’s low hardness and high elasticity and ensuring non-marking usage and touch comfort.

TUBALL™ SWCNT-based nanocomposites and RTV-2 materials were used to fabricate multilayer electronic skin (e-skin) micropatterns via additive manufacturing. SWCNTs provided reliable electrical pathways with low resistivity in micropattern geometries, enabling scalable, low-cost, and flexible e-skin prototypes with promising mechanical and sensing performance.
TUBALL™ dispersed in Ecoflex allows for improved sensitivity with a range from 0.018 (at 500 kPa) to 0.15 kPa⁻¹ (at 5 kPa). The developed sensor accurately detects abnormal activity patterns, such as sudden stops or irregular gait, thereby alerting users to potential safety concerns.
SWCNT/transition metal hybrid nanostructured electrodes was produced. These electrodes exhibit excellent electrothermal properties and flexibility, making them ideal for wearable electronics, semiconductors, energy storage, and catalyst research.
TUBALL™ forms liquid crystalline polyelectrolyte solutions without superacids, enabling safer, scalable production of conductive yarns and coatings. The resulting fibers demonstrate exceptional mechanical (up to 1179 MPa tensile) and electrical (~1.0 MS/m) performance, suitable for wearable electronics such as biometric sensors
The body-heat-powered wearable device offers portable, continuous, wireless monitoring of electromyogram and electrocardiogram captures. TUBALL™-based TEGs show stable performance for 7 days, harvesting a high open-circuit voltage of 175–180 mV from the human body to power wireless bioelectronics for continuous signal detection.
A novel smart contact lens enables noninvasive cholesterol monitoring through tear analysis, offering a convenient alternative to blood tests. The integrated biosensor, enhanced with TUBALL™ SWCNTs, provides high sensitivity and wireless signal transmission.
