On-the-go electronic COVID-19 test debuts at CES

“The ViraWarn [Baltimore, MD] breath analyzer, is a portable device that can detect numerous viruses — like COVID-19, influenza, rhinovirus and the respiratory syncytial virus (RSV) — in less than 60 seconds.  . . . .  ViraWarn leverages charge transference (CT) technology, a combination of advanced biosensors and proprietary edge AI algorithms. A carbon filter in the mouthpiece of the device sieves out large particles like ammonia and other volatile organic compounds (VOCs) and only allows virus-sized particles to pass through to Opteev’s proprietary silk-based chemiresistive sensor. These particles are charge carriers that, when they come in contact with the biosensor, cause a change in the conductivity and electrical parameters of the biosensor. This output electrical data is then sent from the biosensor to an internal AI processor that diagnoses a positive or negative result. A HEPA filter cleans the air released from the back of the device.”  Note, this device does not distinguish different viruses, but tells if virus is present.   MORE WITH VIDEO
