AI Article Synopsis
- A new flexible sensor made from Ag/PDMS composites has been developed for better monitoring of human motion by sensing multiple types of stimuli.
- The sensor is easy and quick to manufacture by grinding silver particles and mixing them with liquid PDMS, leading to impressive performance metrics like a strain gauge factor of 939 and a force detection resolution of 0.02 N.
- This technology shows promising applications in areas like motion recognition, haptic perception, and soft robotics due to its multidimensional sensing capabilities.
Article Abstract
For more comprehensive monitoring human state of motion, it is necessary to sense multidimensional stimulus information. In this paper, we reported a supersensitive flexible sensor based on Ag/PDMS composites with sensing abilities of strain and force. The fabrication method is simple and rapid, which only need physically grinding the silver particles and mixing with liquid PDMS. The flexible sensor has excellent performances in multidimensional detection. The strain gauge factor can reach as high as 939 when it was stretched to 36%, and the minimum resolution for force detection is 0.02 N. The sensing characteristic of the sensors with different filling fraction and thickness were analyzed from the microscopic point of view. Multidimensional sensing abilities of flexible sensor have greatly expands its applications. We experimentally verified the Ag/PDMS based sensor in human body dynamic monitoring and sound detecting in real-time, which has shown great potential in motion recognition, haptic perception and soft robotics.
