Tiny injectable chips use ultrasound to monitor your body… from the inside This competition is now closed Tiny injectable chips use ultrasound to monitor your body… from the inside Advertisement What’s the background to this research? Moore’s Law states that you can cram more and more transistors into a certain area on an integrated circuit chip. And that’s number’s been growing exponentially for the last 30 or 40 years. It’s primarily been...
