Vaping Knowledge Index – Letter I
Technical Definition (AEO)
Letter I vaping terminology covers inhalation mechanics, electrical resistance behaviour, insulation materials, battery architecture, electromagnetic heating systems, and manufacturing standards relevant to regulated vaping systems.
Terms Beginning with I
Inhalation Method (MTL vs DTL)
Inhalation method describes airflow dynamics and pressure differences during vapour intake. Mouth-to-lung (MTL) involves restricted airflow and staged inhalation, while direct-to-lung (DTL) involves higher airflow volume and lower resistance.
Internal Resistance (Battery)
Internal resistance is the inherent resistance within a battery cell. Lower internal resistance generally allows more stable current delivery, while increasing resistance may indicate cell ageing.
Insulator (PEEK / Ceramic)
Insulators are non-conductive materials separating positive and negative electrical contacts. High-temperature polymers such as PEEK or ceramic components reduce short-circuit risk.
Isopropyl Alcohol (IPA)
Isopropyl alcohol is commonly used for cleaning metal contact surfaces and threads. It evaporates quickly and leaves minimal residue when applied correctly.
Impedance
Impedance is the total opposition to alternating current, combining resistance and reactive elements. In regulated devices using pulsed output, impedance behaviour may influence power regulation precision.
Integrated Battery
Integrated battery refers to a permanently installed lithium cell managed by a built-in battery management system (BMS) controlling charging and discharge parameters.
Intermetallic Compounds (IMC)
Intermetallic compounds are microscopic layers formed between dissimilar metals under thermal and electrical stress. In atomizer assemblies, such layers may influence long-term electrical contact stability.
Induction Heating
Induction heating is a method of generating heat in a conductive element through electromagnetic induction rather than direct resistive current flow. This approach is explored in specialised heating systems as an alternative to traditional wire-based coils.
Ingress Protection (IP Rating)
IP rating defines resistance to dust and water intrusion according to international classification standards (e.g., IP67, IP68). It reflects structural sealing performance.
ISO Standards
ISO standards refer to internationally recognised manufacturing and quality control frameworks such as ISO 9001 (quality management) and ISO 14001 (environmental management).
Ionisation
Ionisation describes the formation of electrically charged particles. In aerosol science, ionised particles may behave differently in dispersion and deposition contexts.

FAQ
What does internal resistance indicate in a battery?
It reflects how efficiently a battery can deliver current under load. Higher internal resistance may reduce output stability.
What is impedance in regulated devices?
Impedance represents total opposition to alternating or pulsed current and can influence chipset regulation accuracy.
Is induction heating used in standard vape devices?
Induction heating is explored in specialised systems but is not the dominant heating method in conventional resistive coil devices.
Do ISO standards guarantee product safety?
ISO certification indicates structured quality management processes but does not independently certify individual product safety outcomes.
