Bhattacharya, R. (author), de Kok, M.M. (author), Zhou, J. (author), TNO Industrie en Techniek (author)We present a simple fabrication process that produces polymeric charge storage devices directly onto a textile surface. By using a coating of poly-(3,4-ethylenedioxythiophene):poly(styrene sulphonic acid) (PEDOT) as a solid electrolytic layer deposited between two woven silver coated polyamide yarns, we have created a simple polymeric textile...article 2009

Debrauwer, P. (author), Emmelkamp, J. (author), Bolt, P.J. (author), TNO Industrie en Techniek (author)This paper describes a model and experiments to validate it for the design of bubble free chambers and channels in microfluidic chips. When handling liquids in a microfluidic chip problems may arise with entrapping air or liquid. These air and liquid bubbles deteriorate the efficiency of the process on a chip and diminish the control of liquids...conference paper 2009

(author), van Bommel, K.J.C. (author), TNO Industrie en Techniek (author)Polymer brush coatings, consisting of polymer chains covalently attached to a surface and being less than a hundred nanometer thick, allow the creation of functional surfaces without altering the inherent bulk properties or appearance of a product. Surface properties depend on the type and length of the polymer used, as well as on the grafting...article 2009

Asadi, K. (author), de Boer, T.G. (author), Blom, P.W.M. (author), de Leeuw, D.M. (author), TNO Industrie en Techniek (author)Organic non-volatile resistive bistable diodes based on phase-separated blends of ferroelectric and semiconducting polymers are fabricated. The polarization field of the ferroelectric modulates the injection barrier at the semiconductor-electrode contact and, hence, the resistance of the comprising diodes. Comparison between the on- and off...article 2009

Slaghek, T.M. (author), Timmermans, J. (author), Jetten, J.M. (author), TNO Kwaliteit van Leven (author)TNO has created a 'release on demand' technology in which matrix particles are formed from biopolymers crosslinked into a three-dimensional network. The particles release compounds only when triggered by stimuli such as temperature, pH, humidity or certain bacterial metabolites. This gives efficient use of active ingredients and prevents...article 2008
