Radiation shielding material built on melanin instead of lead.

Melanin absorbs energy across a broad band of wavelengths and dissipates it as heat. We refine the pigment to high purity, disperse it through a eco-friendly matrix, and process the composite into a sheet. The sheet is then cut and sewn into a prototype shielding garment, so the same material can be judged both as raw stock and as a wearable.

Three development targets define the programme.
Weight: a full garment set in the 1 kg class, against 5 kg or more for a conventional lead apron set - in an interventional suite that load sits on the clinician's spine for every case.
Composition: no lead at all, removing the toxicity and disposal burden that lead-based shielding carries with it.
Regulatory: clearance as a medical device under the classification that applies to shielding garments.

The material is at the development stage. Sheet fabrication methods and shielding performance are being iterated and measured to fix the final specification. Quantitative figures - shielding rate, lead equivalence, attenuation by tube voltage - will be confirmed after certification testing, and are not presented here as achieved performance.

At the booth, visitors can pick up the sheet samples and the prototype garment and judge the weight directly. Two further melanin materials are shown alongside: PHOTOSHIELD CORE, a high-purity melanin cosmetic ingredient supplied B2B, and MELANOIR BLACK, a melanin-pigmented tattoo and PMU ink.

We welcome conversations with interventional and radiology teams, garment and medical device manufacturers, facility integrators, distributors and research partners.

Note: the three product lines are separate and do not share raw materials.

RELIVON is a non-medical Recovery & Conditioning System that combines therapeutic ultrasound and electrical stimulation to support muscle recovery and performance conditioning.

Designed for athletes, fitness centers, personal training studios, sports science laboratories, rehabilitation exercise centers, and professional performance facilities, RELIVON helps manage muscle fatigue and discomfort after exercise while improving overall conditioning efficiency.

Powered by our proprietary CUE Conditioning™ Technology, RELIVON offers three Combine Modes that allow users to select the most appropriate conditioning program according to individual needs. It can be used before exercise for warm-up, after exercise for recovery, or as part of a regular muscle conditioning routine.

Its intuitive touchscreen interface, compact design, and user-friendly operation make it suitable for both professional and commercial environments. RELIVON is designed to integrate assessment, training, and recovery into one efficient workflow.

RELIVON is KC-certified as a non-medical device and is intended for use in sports teams, fitness clubs, performance centers, universities, research institutes, and wellness facilities.
