Dr. Nikos Petrellis talks to us about his work in developing electronic circuits to convert sensor outputs from analog to high resolution digital data. He explains the importance of portable, low cost, and diverse modules that can be applied to existing, perhaps older technology, systems.  We talk about healthcare applications of converting and correcting  analog data derived from existing wearable sensors  in real time without the need of costly upgrades to hospital equipment. Dr. Petrellis presents his future projects including developing an easy to use interface and sensors for elderly person assistance. This will monitor vitals and detect an emergency, or simply aid healthcare professionals in diagnosis. Interviewed by Venetia I. Kyritsi for Tech Talks Central.
