#2012 / Detection Devices for Novel Coronavirus

Novel Coronavirus infection rates decreased over the last few weeks, and several countries are planning to ease stay at home restrictions that will allow some businesses to open. The global economy is in a free fall as both small and large companies struggle to survive. There is no specific treatment for coronavirus, and a vaccine is still months away. Virus testing for Coronavirus is key, but it’s difficult to administer to millions of people. Polymerase Chain Reaction (PCR) is a technique used to amplify small segments of DNA; in layman’s terms, once you have your throat swabbed during a Coronavirus test, the swab is ready for polymerase chain reaction testing. This test is not cheap, and PCR testing is not 100% accurate. A positive test result is a 100% accurate but 30% of the time you can receive a false negative result meaning that people with an active COVID-19 infection still test negative for the disease.
The PCR test must be conducted by medical experts with specialized equipment. There will be a simple and less expensive test in the future and Electronics could play into this new test. I am not an expert in the medical field, but I am in microelectronics. Is it possible to develop an electronic sensor that can detect the coronavirus? Let’s expand on that.
An electronic diagnosis for the disease………
Forehead thermometers with digital readings make it easy to measure body temperatures. Oxygen sensors measure oxygen concentration in blood. Both these devices are available in drug stores and Amazon at a reasonable price. Can we develop a hybrid device that can measure a person’s body temperature and oxygen level in their blood? The device could be small enough to attach to your body and install a Bluetooth module. The device can send data to a control unit periodically and send a notification when parameters are exceeded. Let’s put a dollar figure on this…
Hardware components for this device are very practical, and the cost could be inexpensive depending on volume production. The software can mimic the packages used in digital thermometers and oxygen sensors, and there is a lot of clinical data available for the analysis. Current AI technologies can analyze the data.
This is a practical idea but it requires a lot of time and money to reach the approval stage. Until then, we will have to visit hospital or urgent care facilities for Covid-19 testing. If there is any medical device that is created for Covid-19 testing, it could open new doors for digital disease detection.
