#2014 / Detection Devices for Novel Coronavirus, Part II

In the previous newsletter, I wrote about the possibility of using our electronics advancements to create detection devices for Novel Coronavirus. I received many comments and ideas for these new medical devices. Several commented on current electronic projects intended to develop detection and diagnosis equipment.
The idea is to create a wearable electronic sensor that attaches to your body. The substrate requirements are different from those used in traditional materials (polyimide films or PET films). Device substrates have to be flexible and elastic to remain attached during body movements; urethane and silicone rubber could be an option. Larger sized devices will require a permeable substrate to address moisture from sweating. One option for this basic material is to use adhesive bandages along with an appropriate coating material or glue.
The printed circuit boards copper foil (standard conductor material) is not suitable for a wearable device because of its poor elasticity. Using meander patterns as conductors can improve the copper foil circuits’ elasticity, but it is not enough for general use. One alternative for wiring electronic devices is screen-printable conductive ink. The elasticity from the conductive ink can increase by adding a rubber component for the binder matrix.
Multiple electrode patterns used in sensor modules are needed to continuously detect temperature, oxygen levels, perspiration and more. The sensors can’t detect coronavirus, but the data sent to wireless devices and picked up by an Artificial Intelligence chip can be analyzed. The results can trigger an early detection alarm if the user has symptoms associated with the coronavirus. The primary feature of this diagnosis system is a continuous monitoring of your health and vitals during the infection. The AI devices learn as more data is analyzed, and accuracy will be improved.
The hardware will not require any unique creation for use as the module and its cost can be less than $100 once volume production is scaled. Printable & Flexible Electronics will play a key role in building the devices. The sensor parts should be disposable, because they are attached on human skin. The necessity for early detection is essential, and this device could fill that need. Once operational, it can detect and monitor all your health for almost anything with a quick update and download. I can see every major retailer offering this product for sale.
