We have developed a novel three dimensional tactile sensor based on vertically aligned carbon nanotubes. The carbon nanotubes were directly synthesized on silicon microstructures and these CNTs-on-microstructures were integrated to flexible polydimethylsiloxane layers. Each tactile sensor has four sensing parts and the direction of force can be detected by monitoring the increase or decrease of electrical...
In this work, we report the design, fabrication and in-vitro testing of a novel microneedle-based high sensitivity non-enzymatic glucose sensor for diabetes testing application. It consists of 15 by 15 sharp silicon microneedle array (> 300 µm tall) and multi-walled carbon nanotube (MWCNT) forest electrodes coated with platinum nanoparticle. The Pt nanoparticle coated MWCNT electrodes significantly...
The vertically aligned carbon nanotube (CNT)-bundle is utilized as a mechanical buffer for inertial micro-switch to extend the contact time and therefore to obtain reliable and stable output signals. The CNT bundles are directly synthesized on two facing surfaces of both movable- and stationary electrodes by patterning the catalyst on released microstructures and the following thermal chemical vapor...
