96. Smart Health Tracking Tattoos

The Next Byte Podcast · 15 Nov 2022 · 21m

What this episode covers

Hosts Daniel and Forbode discuss research from Carnegie Mellon University and the University of Coimbra on 'smart tattoos'—flexible, printed bioelectronic patches that track biometric data. They detail the use of eutectic gallium-indium (EGaIn) alloy to create a conductive gel that combines the comfort of dry electrodes with the signal integrity of gel electrodes. The hosts highlight the technology's ability to last several days through daily activities like bathing and exercise, outperforming traditional silver-silver chloride electrodes in trials.

    Episode Twenty-Seven: Simon Wanstall

    Simon Wanstall, a PhD student at the Edinburgh Centre for Robotics and R&D engineer at TouchLab, discusses his work on soft robotic prosthetics and bio-inspired design. He explains how current myoelectric arms are heavy and slow due to hard materials, and details his development of rapid-manufacture strain sensors using laser-etched graphene and silicone to improve sensory feedback. Wanstall also describes Wayne, a bio-inspired soft robot inspired by ragworms, and his industrial placement at TouchLab creating e-skin technologies like the Eidermis and triaxial shear sensors for hazardous environment robotics.
