Electronic Sensor for Bacteria Detection

Electronic Sensor for Bacteria Detection

August 14, 2019 5 By Stanley Isaacs


The sensor’s structure is designed in such a way that it holds the droplet in place so the droplet doesn’t move. And we showed that the pinning of the droplet in place is very important for robust measurements, so we have very small data variation and very small noise. In comparison with traditional methods for saying if bacteria is alive
or not our method it’s an electrical way to
tell them apart in a much shorter time. When our droplet it is evaporating the
environment becomes more salty, so bacteria will sense this saltier
environment so they will activate those emergency valves and take some of the
ions from the droplet. When we are monitoring the conductivity of the
droplet stealing of the ions can be detected in the electrical signal.
