촉각센서 적용을 위한 다중 벽 탄소나노튜브 혼합물의 성형 = Dispensing Characteristics of MUCNT mixture for Tactile Sensor Application

다국어 초록 (Multilingual Abstract)

The flexible sensors to mimic human tactile sensation have been focused widely. However, many of these sensors were fabricated through a series of complex processes. Furthermore, economically available sensors are cost ineffective. Recently, simple tactile sensor was proposed using flexible material and conductive material. That is, the conductive material is discharged on the flexible polymer substrate by direct injection technique. When the external pressure is applied to the sensor, the electrical signal of the conductive lines is changed. Consequently, to implement this kind of sensor it is essential to examine dispensing characteristics for the line fabrication. In this regards, we examined the line fabrication characteristics of MWCNT mixture according to the nozzle dispensing conditions. From the experimental results, it was found that the line width of MWCNT mixture decreases as the flow rate decreases and the nozzle moving speed increases.
