We present the first realization of printed capacitive touch buttons and touch pads integrated into the organic coatings on sheet steel. The properties of coated sheet steel relevant for printing are discussed and compared with substrates, commonly used for printed electronics. Different designs and read-out methods for capacitive buttons on sheet steel have been screen printed and their sensitivity...
We introduce various novel techniques for the performance enhancement of nanotechnology-enabled wireless platforms utilizing inkjet-printed graphene thin films, especially for gas sensing applications in this paper. Compared to previously reported results (6% sensitivity after exposure to 500 ppm NH3), we have improved the performance by nearly a factor of 10, increasing the sensitivity to 4.8% at...
In this paper we demonstrate the design and development of a family of low-cost, self-powered, wireless sensor solutions utilizing both analog and digital principles. The sensors will utilize Graphene-based thin films integrated directly into the structure. For an immediately deployable digital sensing solution compatible with current commercial technologies we will utilize the Intel WISP platform,...
Fabrication of 3D mechanical structures is sometimes achieved by layer-wise printing of inks and resins in conjunction with treatments such as photonic curing and laser sintering. The non-treated material is typically dissolved leaving the final 3D part. Such techniques are generally limited to a single material which makes it difficult to integrate high resolution, conformal electronics over part...
