The imagination of a new type of material for the mouth/face mask started last night before going to bed. The idea was about using hard material to keep the mouth from touching the mask. The hard material would have micro holes to receive the form from the air and guide the foram to drop down to a ditch inside the material through down-falling microchannels while keeping the air flowing for breath through up-flowing channels. This way the mask can be re-used after traditional sanitation. The making of the two types of channels inside the material, which could be transparent or not, is imagined to be impossible.
A new idea came right before getting up from bed this morning.
Instead of going through the troubles to invent new manufacturing techniques for making materials with two kinds of inside tunnels, one turning the foam moving down and the other turning the air flowing up for breathing in, three layers of film, hard or soft, see-through or colored, to keep the flows of liquid and air separate, could make the mask practical with reusability. The external layer contains micro holes to let the foam go through. The middle layer blocks the foam and drops them down to the bottom that can be opened to release the accumulated water before sanitation. The internal layer has holes that let the air from the bottom opening between the 2nd and the 3rd layer reach the protected nose.
The medical practitioners and those people who have the need to be near the high risk or the contaminated area to wear and keep changing at certain intervals and let the masks go through the conventional sanitation repetitively.
The material might be easily manufactured by the expertise of Dr. Simon Chen who invented the special glass/film at Missouri University.
Transparent masks make it possible to show the goodwill of smiling and the cleanliness of the medical practitioners. The colored masks are made with material of lower cost for the people not directly facing the patients and their companions.
The mask that is not touching the face could receive droplets from the top gap. The one using the special material mentioned above could have soft material for sealing between the mask and the face.
