Haykozé’s AirRing 49, a contactless biomedical cooling additive for safety helmets, eliminates heat stress for billions of workers, keeping them agile and free.
229m outdoor workers face 19,000 heat-related deaths and 22.85m occupational injuries each year, worsening with rising temperatures [ILO]. Air Ring 49(AR49) is a contactless, ergonomic biomedical cooling additive for outdoor workers to prevent heat-strokes, enjoy working conditions, and recover valuable hours of productivity. Created from 48 prototypes across 3 years, AR49 seamlessly integrates with any safety helmet with two-clicks, uniquely directing airflow to high-sweat areas behind the neck and ears. In collaboration with The University of Hong Kong's Faculty of Medicine, AR49 is proven to effectively lower skin-temperature by 5.1°C and core-temperature by 0.67°C, demonstrating a whole-body cooling effect while avoiding headaches. At 155 grams, AR49 offers up to 15hrs of cooling per charge, ensuring comfort and minimal distraction. Doubling as a neck fan when off-duty, AR49 is waterproof and impact-resistant, pioneering a new standard of safety. AR49 is supported by HKU’s Faculties of Medicine, Architecture and Engineering, trialed and adopted by government and major construction companies, and numerously accoladed e.g.2024 James Dyson Award.
Jeff is Co-Founder and COO of Haykozé, developer of the Air Ring 49 (AR49), an award-winning biomedical cooling innovation preventing heat stress in construction. AR49 secured the prestigious James Dyson Award (National Winner, Top 20 International), Qianhai Youth Entrepreneurship Award, and showcases at the Geneva International Exhibition of Inventions, MEET Taipei, and HKTDC’s E-day.
With faith he drives Haykozé’s engineering, business, and strategy—leading prototyping, fundraising, investor negotiation, marketing, and patenting. Works have been featured by Smithsonian Magazine, MingPao, and HOY TV.
With professional design experience at Ho & Partners Architects in Hong Kong and Mendanha & Sousa Construction in Ghana, he brings international perspective across architecture, product design, and business development. He has also received the Eric Lye Memorial Travelling Scholarship and George William Hong Choy Memorial Scholarship from The University of Hong Kong.
Though, he prefers a shorter biography for himself: “A team’s glue.”
