A new low-cost AI-powered device developed at Heriot-Watt University, Edinburgh, is set to change how skin cancer diagnosis is carried out in rural and underserved regions around the world. Designed to work even without internet access or specialist doctors, this tool could make early detection accessible to millions.

🌟 What Makes This Device Special?

Created by PhD researcher Tess Watt, the prototype uses a Raspberry Pi computer and camera. Patients can take a photograph of a suspicious skin lesion, and the built-in machine learning software compares it against a database of thousands of skin conditions.

• Accuracy: Currently up to 85% accurate in identifying skin abnormalities
• Offline Use: Works without internet connectivity to serve rural regions
• Instant Analysis: Provides a quick, AI-generated assessment of lesions
• Integrated Care: Links with local GP systems to start treatment plans on time

This innovation is especially aimed at regions with limited or no dermatology access, ensuring early detection where traditional healthcare services are scarce.

🏥 Healthcare from Home

According to Tess Watt, home-based health monitoring is critical as GP wait times increase worldwide.

“If we can empower people to monitor skin conditions from their own homes using AI, we can dramatically reduce delays in diagnosis,” she explained.

The device has been tested at Heriot-Watt’s advanced health and care technologies suite, with talks underway with NHS Scotland for ethical approvals to begin real-world trials.

🚀 Future Plans and Global Potential

The long-term vision is to roll out the device first in rural Scotland, followed by remote areas across the globe. The tool can also help patients unable to travel, with family members assisting in capturing and submitting images.

Supervisor Dr. Christos Chrysoulas highlighted the resilience of the system:

“E-health devices must work independently of external connectivity to ensure continuity of patient care. Affordable devices like this must maintain essential clinical operations even during network failures.”

🔍 Why This Matters to Doctors and Healthcare Professionals

Early detection of skin cancer can save lives, but access to dermatology is still a challenge in rural and underserved communities. This device can:

• Reduce delays in diagnosis
• Support GPs and healthcare workers in remote areas
• Empower patients to self-monitor at home
• Ensure continuity of care without dependence on internet networks
