IEC TS 62607-6-23:2025, which is a Technical Specification, establishes a standardized method to determine the key control characteristic (KCC):
• carrier mobility and sheet resistance
for graphene thin films by:
• Hall measurement.
The carrier mobility is derived by the product of the Hall coefficient and the electric conductivity and the sheet resistance is derived by the product of the longitudinal resistance and the aspect ratio of a Hall device.
• The method is applicable for graphene thin film Hall devices with length and width greater than 100 micrometers.
The document is developed to complete the fabrication and measurement of devices using cost-effective processes and equipment. Due to the high cost and low cost-performance ratio of photolithography processes and equipment, this document does not utilize photolithography processes and equipment.

– children playing with the appliance.
Attention is drawn to the fact that
– for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements can be necessary;
– in many countries, additional requirements are specified by the national health authorities, the national authorities responsible for the protection of labour, the national authorities responsible for the safety of pressure vessels. and similar authorities.

IEC 63150-2:2025 specifies terms and definitions, and test methods that can be used to evaluate and determine the performance characteristics of kinetic energy harvesting devices for human arm swing motion. Such kinetic energy harvesting devices often have a rotor with eccentric mass to efficiently capture kinetic energy at very low frequency range, but this document is not limited to rotational energy harvesters. These have different power generation mechanisms (such as electromagnetic, piezoelectric, electrostatic, triboelectric, etc.) with different working principles, and their performance is evaluated with motions relevant to human arm swing, in which large-amplitude low-frequency external mechanical excitations prevail.

IEC 63150-3:2025 specifies terms and definitions, and test methods of impact-driven energy harvesting devices of which electric energy is generated by impact force of human walking or running motion under practical human motion. This document is applicable to impact-driven energy harvesting devices embedded in wearables, especially, shoe-mounted energy harvesters, whose main element of the power generation is the impact energy. This measuring method is independent of power generation principles (such as piezoelectric, electrostatic, triboelectric, electromagnetic, etc.). According to typical human motion, power generation performance is measured in the condition of large-amplitude and low-frequency external mechanical excitation.
