The Killer for March 19th, 2022 was ProtonIntel, who is making the world's first continuous potassium monitor for kidney monitoring. They shrunk their electrode by over 1000x while also maintaining its sensitivity in the optimum range, making it now viable for in-human testing. They'll be flying out TODAY (date of publication) from Vancouver to Melbourne to jab themselves with their sensor and get the first measurements in humans. You're listening to the development live and hearing the inside story about the pivotal feat of engineering.
