Description

BioInkSense™ C120 Flexible Carbon Conductive Ink

BioInkSense™ C120 is a high-performance flexible carbon conductive ink engineered for fabrication of wearable biosensors, flexible printed electronics, stretchable sensors, and disposable diagnostic devices. The formulation combines excellent electrical conductivity with exceptional mechanical flexibility, enabling reliable electrical performance under repeated bending, twisting, and mechanical deformation.

The optimized polymer-carbon composite provides excellent adhesion on flexible substrates while minimizing conductivity loss during cyclic mechanical loading. C120 is particularly suited for next-generation wearable healthcare devices, epidermal sensors, flexible microfluidic systems, and printed electronic circuits requiring long-term mechanical durability.

The formulation is optimized for fabrication of working electrodes used in amperometric, voltammetric, potentiometric, and electrochemical impedance sensors.
