Enige tijd geleden werd er in het tijdschrift Cellulose gepubliceerd<\/a><\/noindex> een studie van Finse wetenschappers die vertelden over de creatie van optisch glasvezel uit cellulose. Het idee om lichtgeleidend vezelstructuren te cre\u00ebren, werd voor het eerst gevormd in 1910. Veel decennia later zijn glasvezelkabels een alledaagse realiteit en een onmisbaar middel geworden voor energiezuinige informatieoverdracht over duizenden kilometers.<\/p>\n

\"Er<\/p>\n

De door Finse wetenschappers ontwikkelde cellulosevezel is niet geschikt voor telecommunicatiedoeleinden. De lichtverstrooiing is te hoog - tot 6,3 dB per centimeter in de open lucht bij een golflengte van 1300 nm. In water nam de verstrooiing toe tot 30 dB per centimeter. Maar juist deze eigenschap blijkt het meest gewild. Dergelijke cellulosevezels, dankzij hun aangeboren vermogen om te absorberen, zullen een waardevolle en handige oplossing blijken voor vochtigheidsmetingen.<\/p>\n

De wereld van slimme sensoren en apparaten met internetverbinding kan profiteren van flexibele, uitgestrekte en eenvoudige, evenals energiezuinige sensoren voor vochtigheidsmetingen. Dergelijke oplossingen kunnen worden ingebouwd in funderingen van gebouwen en constructies om de luchtvochtigheid in monolithische structuren te controleren, bijvoorbeeld om het niveau van overstromings- en grondwater te bewaken. Draagbare elektronica kan worden aangevuld met vochtigheidssensoren voor het lichaam en kleding, wat nuttig zal zijn in het dagelijks leven voor het volgen van de toestand van kleine kinderen en voor liefhebbers van actieve recreatie.<\/p>\n

\"Er<\/p>\n

Optische vezels van kunststofmaterialen hebben al een niche veroverd in sensoren voor het verzamelen van seismische gegevens, inclusief zelfs het volgen van verkeersstromen in steden<\/a><\/noindex> en vooral luide geluiden op straat (schoten, geluiden van ongevallen en dergelijke). Met de komst van cellulosevezels zal het toepassingsgebied van flexibele, thermisch stabiele en stevige optische kabels zich uitbreiden naar vochtigheidsmonitoring, iets wat kunststof glasvezels in principe niet kunnen.<\/p>\n
