| 제목 | Sensing Mechanisms of Pressure induced CNTs Coated Colloidal Sensors |
| 초록 | We have systematically investigated the electrical conductance change of Carbon Nanotubes (CNTs) coated polyurethane colloidal sensor under external pressure. The external pressure induces structural deformation of the colloidal sensors, especially coated CNTs. So, we have designed several models characterizing structural deformation of CNTs under compressive/tensile strains and investigated responding their electrical conductance. In addition, we have considered the effects of electrodes induced external electric field and CNT-CNT intertube contact stimulated by external pressure. In these works, we have clearly elucidated the operating mechanism of CNTs coated colloidal sensors is based on the electrical conductance changes of CNTs induced by structural deformations under external pressure, which strongly affects band structures and electron transport characteristics. |
