96. Smart Health Tracking Tattoos
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.
