Magneto/Pressure sensitive dual-mode sensor with enhanced sensitivity and modality enabled by sandwich structure |
| 초록 |
Nowdyas, the need for multi-modal tactile sensors is increasing for emerging human-interactive applications. In this work, we present a dual-mode, magneto-sensitive pressure sensor that can detect a magnetic field in a remote mode and pressure in a contact mode, with excellent sensitivity and stability. The dual-mode sensor consists of a magnetic composite elastomer integrated with two flexible pressure sensors. An external magnetic field can exert force on the magnetic composties interfaced with the pressure sensor, accordingly changing the resistance of the pressure sensor. In order to detect not only the intensity but also the direction of the magnetic field, we further employed a sandwich structure, that is, pressure sensor-magnetic elastomer-pressure sensor so that magnetic elastomer would press different sensors under different magnetic field direction. Our device showed an exceptionally high magnetic sensitivity compared to previous studies. |
