    "device_name": "Device for the Gas-Discharge Visualisation of an Image (GDV device)",
    "goal": "Provide a non-invasive diagnostic method that captures the electromagnetic-induced gas-discharge glow of biological objects and extracts physiological and psychological parameters.",
    "problem_addressed": "Traditional Kirlian photography requires photographic paper, long development times, and yields low-resolution, low-sensitivity images that hinder quantitative medical diagnostics.",
    "concept_summary": "A high-voltage electrode creates an electric field across a dielectric plate on which the object (e.g., a fingertip) is placed. The field induces a gas-discharge glow around the object. An optically coupled camera records the glow in real time, and computer software analyses multi-parameter images to produce diagnostic statements about stress, health, or psychophysical state.",
    "detailed_description": "The GDV system consists of a high-voltage power supply, a transparent conductive electrode (often a metallic mesh), a dielectric plate with a transparent insulating coating, and an optical fiber light guide that directs the discharge glow to a television camera. The camera feeds video signals to a computer where specialised software calculates parameters (e.g., area, intensity, dynamics) and correlates them with physiological or psychological conditions. The device can be used on living tissue, non-organic objects, and is marketed for stress monitoring, medical treatment tracking, and psychical assessment.",
