Hospital clothing and privacy linked with hygiene,economy and smart materials.

I have a master degree in fashion design.I intend to apply for a PhD program in united kingdom.I suggested this topic to the head of department there,she recomended studying one or all the aspects mentioned in the title.I want to conduct an experemental research ,of course, away from textiles,because I dont have much background in it.Using an illustration software such as (Skechup) would be a great idea.also,may be if we conduct it based on age group such as childeren or the elderlies.I prefer to exclude the males from my sample,I feel more comfortable with females.The professor asked me as a good start ,to see wheather there are similar studies about this topic had been conducted.A good source of information is the clothing and textiles journal.
