This paper presents a concept of a micro thermal sensor to be used for defect inspection of a smoothly-finished surface such as a bare wafer or a hard disk. In the proposed concept, existences of the defects on a measurement surface will be detected by scanning the surface with the micro thermal sensor, which is utilized to detect the variation of the thermal flow in-between the sensor surface and...
The harvest of heat energy using a thermoelectric (TE) effect is one of the potential methods for body area network power source. This paper demonstrates a new approach of a chemical electroplating deposition process to fabricate a self-endurance flexible TE generator without top and bottom sustaining substrate. According to that, an idea of horizontal Y type TE cells instead of column π type structure...
In this study, we present the characterization and the modeling of transparent silver nanowire thin-film heaters in terms of their transient thermal response when subjected to Joule heating and their electrical properties. The electrical properties, which showed a conductance-temperature dependence that is reduced down to a factor of 2 compared to the value for bulk silver, could be modeled accurately...
Pd is a unique substrate to explore graphene growth. Pd is a well-known “carbon sponge” which have potential to grow graphene with semiconducting properties in nature. Here, we reveal a solid phase reaction process to achieve Pd assisted graphene growth in nanoscale by in-situ transmission electron microscope (TEM). Significant structural transformation of amorphous carbon nanofiber (CNF) incorporated...
Graphene has already been verified to have potential applications in sensor development due to its unique properties, such as large specific surface area, high carrier mobility, conductivity and optical transparency. Here, we discuss our development of a micro bubble generator that could be used to generate and actuate micron-scale bubbles based on monolayer graphene made from chemical vapor deposition...
Effective manipulation and rapid injection of nanosensor with high cell viability have great significance to biological and biomedical applications such as drug delivery and cells biology. This study presents manipulation of a magnetic nanosensor with a temperature indicator and immobilization onto cell surface using glass nanoprobe by Coulomb's force. The nanosensor is stained by Rhodamine B as the...
We are proposing a new active thermal-electronic device, the phonsistor (= phonon transistor). This device operates by means of thermal or hot electron coupling between adjacent domains containing metal-insulator transition (MIT) material. The MIT resistor itself has got thyristor-like I–V characteristics due to the high electric field and/or Joule heating and extremely strong step-like resistance...
