This paper describes novel glass micropipette thermal sensor fabricated in a cost-effective manner and thermal conductivity measurement of carbon nanotubes (CNT) thin film using the developed sensor. Various micrometer-sized sensors, which range from 2 µm to 30 µm, were produced and tested. The capability of the sensor in measuring thermal fluctuation at micro level with an accuracy of ±0.01°C is...
We have clarified the strain-rate dependence of mechanical properties of Au thin films with thicknesses less than 100 nm. Stress-strain relations of Au films were examined by tensile tests using the Electrostatically Actuated NAno Tensile testing devices (EANATs). Young's modulus showed a substantially smaller value of 30 GPa in average compared to bulk material, and it had no strain-rate dependence...
Electrowetting on dielectric (EWOD) is useful in manipulating droplets for digital (droplet-based) microfluidics, but its high driving voltage over several tens of volts has been a barrier to overcome. This paper presents the characteristics of EWOD device with aluminum oxide (Al2O3, εr≈10), deposited by atomic layer deposition (ALD), as the high-k dielectric for lowering the EWOD driving voltage...
