The way the spread of Covid virus going on all over the world which is quite alarming and it appears there will be no end to the virus, on the contrary it will increase further in strength.
May I sound our great scientists in the world to do a research work to develop a sensor on a pen built-in to sense or detect signals received from Coronavirus positive at a certain distance when a person approaches you.
Will it be possible? I being a scientist I thought nothing is impossible in this world when a man has already stepped in the moon? Probably they have not thought of such an invention.
Later if successful, they may think to develop variants of sensors for different types of virus? This will be an achievement.
