Listen now (16 mins) | This week we have the honor to interview Carlos Olguin, the CEO of LogicInk a leading wellbeing biosensor company for everyone. Powered by programmable chemistry and biology, LogicInk is a San Francisco-based company developing biosensors called Signals. LogicInk Signals come in two form factors. In one case they can be worn like a temporary tattoo with a colorimetric display that dynamically changes to inform users about a condition of interest (e.g. get a safe healthy daily UV dose from the sun). A second form factor, currently in development, is a thin device with a sterile applicator that is licked and once inserted into the device it gives users a quick one-time health indicator. Applications include the readout of electrolyte levels and how that can correlate to hydration levels.
