| 英文摘要 | In intelligent robotics and artificial skins, tactile sensors are needed to detect the pressure and slip signals. Mostly, pressure sensors (e.g. capacitive type) and slip sensors (e.g. piezoelectric type) are individually used to acquire the signals in different directions, which would increase the complexity of whole system [1]. Ferroelectrets are polymer-based space-charge electrets with ferroelectric effects, exhibiting a number of advantages in sensor applications [2]. In this work, a ferroelectret system based on a dual-structure was studied for sensing force signals in both normal and tangential directions with the same sensor unit. The system consisted of two layers A and B. The A on top had a cellular structure with rough outer surface, and B on bottom had a cellular structure with smooth surface. In force sensing, the top layer A was facing the measurand force, and it could detect the normal signal (pressure) and as well the tangential signal (sliding friction) due to its rough surface, with output YA. The bottom layer B could only measure the normal signal that was transferred through the layer A, with output YB. YB was considered as the pressure signal, and (YA - YB) was the friction signal. An improvement of the sample preparation and signal processing is suggested for future applications in the intelligent artificial-skins. |
