Innovative Applications of Open-Circuit Electroluminescent (OCEL) Technology Platform

Introduction
Modern sensing technologies increasingly demand compact, precise, and versatile platforms capable of measuring a wide range of physical and chemical properties. AhuraTech’s Open-Circuit Electroluminescent (OCEL) technology represents a major advancement in this field. By operating in an open-circuit configuration, OCEL enables light-based sensing allowing materials themselves to influence and modulate light emission This unique behavior makes OCEL a highly adaptable technology platform capable of detecting numerous physical properties across liquids, solids, and surfaces.

Core Technology Overview
OCEL light measurements using alternating current in an open-circuit electroluminescence configuration represent an innovative technology developed at AhuraTech. This approach is based on varying levels of energy transfer through an EL-active component, which proportionally produces different intensities of light. These light levels are subsequently measured using a range of light sensors.

Unlike conventional systems—where electromagnetic energy is generated from a stable pulse generator and grounded, resulting in consistent light intensity—the OCEL system does not ground the electromagnetic pulse. As a result, the energy transfer strongly depends on the materials connected to the EL-active component, which act as energy sinks. The flow of energy through these sinks causes the EL material to emit light.

Recognizing that different materials have varying capacities to act as energy sinks, the OCEL technology modulates energy transfer based on the distinct properties of the samples under investigation. By altering a specific property of a sample, the system produces unique light signals, which are then detected and reported by light sensors.

In principle, the OCEL platform is capable of measuring virtually any property of a given sample, provided that all other properties remain constant across the samples being analyzed.

AhuraTech has successfully employed the OCEL platform to measure numerous sample properties, including weight, volume, surface roughness, electrical conductivity, dielectric capacitance, polarity, micro-scale groove or crack visualization, fingerprinting, critical micelle concentration, and liquid level in reservoirs, among others.
