Surface and Volume Resistivity Measurement
topic
Surface resistivity of conductive textiles is measured using four-probe or concentric ring electrode configurations under defined contact pressure, humidity, and temperature, expressing results in ohms per square normalised to specimen geometry; volume resistivity measurements use through-thickness electrode arrangements to characterise z-direction conductivity of multilayer conductive composite structures.
Role
Provides the fundamental electrical characterisation of conductive and antistatic textiles, enabling classification of materials from insulating (above 10¹³ ohms per square) through antistatic (10⁶ to 10¹¹) to conductive (below 10³) for electrostatic dissipation, EMI shielding, and electronic textile applications.
