Handheld acoustic device for multi-layer skin material characterization

Overview

Heriot-Watt University has developed a pioneering handheld acoustic device designed for non-invasive multi-layer characterization of skin materials. This device uses sound waves to assess the elasticity and viscoelasticity of different skin layers, offering a rapid and unbiased evaluation of tissue health. It excels in detecting sub-surface changes indicative of inflammatory skin conditions, like eczema, before they manifest visibly on the skin's surface. The device's interpretive sensing and analytics system allows for high-resolution, simple measurements, setting it apart from existing modalities.

Technical specifications

• Non-invasive sensing: Utilizes acoustic waves to measure skin layer stiffness and fluid content.
• High-resolution analytics: Provides detailed insights into mechanical properties such as swelling and stiffening due to inflammation.
• Personalized baseline comparisons: Uses the patient as their own control, allowing for before/after therapy comparisons or assessments between different body parts.
• Compact design: Handheld and portable, ideal for clinical and personal use.
• Material safety: Developed with biocompatible materials to avoid inflammatory reactions, with ongoing testing to ensure safety and specificity.

Technology readiness level

The technology is currently at TRL 5, having been validated in laboratory settings and with human volunteer data. Further trials and clinical investigations are underway to expand the sensitivity data and confirm material safety, with enhancements planned using 3D printing for device customization.
