    Abstract : Tactile perception is considered an important contributor to the overall consumer experience of a product. However, what physical properties that create the specifics of tactile perception, are still not completely understood. READ MORE

  2. 2. Adhesion and Friction - a Study on Tactility

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Kenneth Duvefelt; KTH.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adhesion; finger; friction; humidity; material; model; tactile friction; tactility; Machine Design; Maskinkonstruktion;

    Abstract : Although we are surrounded by hundreds of surfaces we can still distinguish them from each other simply by touch. The tactile information, interpreted by our brain and given by our fingers, is precise, but to put words to the sensation is very difficult — is it smooth, sticky or harsh? We do not only perceive surfaces differently, we also describe them in our own way. READ MORE

  3. 3. Formation and properties of polyelectrolyte multilayers on wood fibres  influence on paper strength and fibre wettability

    University dissertation from Stockholm : KTH

    Author : Rikard Lingström; KTH.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; polyelectrolyte; multilayer; adsorption; reflectance; contact angle; dynamics; paper; mechanical properties; individual; wood fibre; NATURAL SCIENCES Chemistry; NATURVETENSKAP Kemi;

    Abstract : The work in this licentiate thesis examines the adsorption of polyelectrolyte multilayers (PEM) onto wood fibres as a new way to influence the properties of the fibre surfaces and hence the fibres. Fundamental aspects of PEM formation on wood fibres have been studied, and discussed in terms of paper strength and wood fibre wettability. READ MORE
