BrushCoin: Patent-Pending Smart Toothbrushing Verification and Digital Reward Technology for Oral Healthcare
- Technology Overview BrushCoin is a patent-pending oral-health technology designed to encourage consistent toothbrushing through sensor-based activity monitoring and digital incentives. The proposed solution combines brushing movement detection, software-based activity assessment, and a digital reward mechanism to support consumer engagement and oral-hygiene habit formation.
- How It Works An early-stage functional prototype uses a toothbrush-mounted motion sensor connected to an ESP8266 development board. Software processes movement information to identify brushing-related activity, while a proof-of-concept reward workflow demonstrates digital token transactions using the Ethereum Sepolia test network. The broader proposed architecture includes privacy-preserving on-device processing, digital twin modeling, and blockchain-supported reward verification. These advanced components remain subject to further development and validation.
- Potential Commercial Applications BrushCoin could complement connected electric toothbrush ecosystems, including smart oral-care devices. Potential applications include consumer engagement programs, personalized brushing incentives, and preventive oral-health initiatives. Integration with existing commercial toothbrush platforms has not yet been established, and clinical benefits remain to be evaluated.
- Development Status and Evidence Technology Readiness Level: TRL 3 — Experimental proof of concept. A functional prototype and demonstration video are available. BrushCoin received a Silver Medal at the 2025 IFIA International Invention and Innovation Competition.
- Intellectual Property International patent application PCT/IB2025/056962 was filed on July 9, 2025, and remains pending. The inventor and patent applicant is Jafar Kolahi Kazerani personally. Dent Hypotheses Ltd is associated with this partnering listing but does not own the patent application.
- Partnership Opportunity The inventor is seeking technology licensing or co-development partnerships with established oral-health companies. Potential next steps include technical feasibility assessment, independent prototype validation, evaluation of compatibility with connected toothbrush platforms, and development of a commercially scalable solution. Any licensing or development agreement would be negotiated separately, with intellectual property ownership and permitted uses expressly defined.
