Two-dimensional force-sensing whisker based on a WGM microbubble resonator
This study presents an all-optical 2D force sensor based on cascaded whispering gallery mode (WGM) microbubble resonators (MBRs). The 2D force sensing system is composed of 2 MBRs connected to a whisker, 2 glass supports, and 2 tapered fibers. By using a characteristic sensing matrix to decouple cross-sensitivity of 2D forces, the sensor achieves high sensitivities to force of 118.14 pm/mN in the x direction and 177.12 pm/mN in the y direction. This work demonstrates the potential of WGM-based 2D force sensors for applications in robotics, artificial perception, and biomedical devices.
