Abstract:

Unfortunately, most Berkovich indentation loading curves are still claimed to follow the Sneddon exponent of 2 on hand most finite element simulations try to support it, even though the experimental exponent 3/2 on h has been hundred folds secured with linear correlation coefficients r>0.999 or often >0.9999 of published loading curves dealing with all kinds of indentation techniques, materials and response mechanisms, since 2000. Authors continued believed in 2 and avoiding their exponent check. Even worse, nano and micro-mechanical parameters continued to be deduced based on the unsupported exponent 2 in a tutorial from NIS for biophysicists, leading to incorrect material properties. Conversely, applications of the correct loading exponent are highly versatile, much more reliable and precise than hardness and modulus. Penetration-resistance provides finer details, which are particularly important for biological/medicinal analysis and mappings of alloys and composites. Importantly, penetration resistance, indentation energy, phase transitions with their transition energy, activation energy and adhesion energy are accessible without iterations. The exponent 3/2 allocates 80% of the applied indentation work for the penetration and 20% for all additional processes. The appreciation of this wealth of unexpected applications presumably requires the physical reason for the new exponent which was still lacking. Fortunately, the deduction of the exponent 3/2 for conical and pyramidal indentations (against textbook claims) can now be given on an elementary basis. The elementary mathematical formalism will be presented. This is new physics that can no longer be denied. It helps avoiding dangerous failures in medicine and technique

Abstract:

Flexible, body-worn healthcare/medical devices have the potential to revolutionize preventive medical care and health promotion. Carbon nanotube thin films are promising electronic materials for transistors, biosensors and other passive components to build such flexible devices because of the excellent electronic and mechanical properties and biocompatibility. In the presentation, we introduce our recent works on flexible transistors and biosensors based on carbon nanotube thin films, including the wafer-scale fabrication and characterization of carbon nanotube thin-film transistors, the improvement of sensitivity of electrochemical biosensors based on redox cycling process, the development of thin film transistor-based biosensors with ultra-high sensitivity and wide dynamic range.
