Instantaneous tiltmeter triggered by dynamic wetting behavior

Abstract A novel instantaneous tiltmeter with dynamic and static monitoring functions is reported that is based on liquid metal dynamic wetting behavior in a bio-fabricated anisotropic microchannel. The proposed system achieves instantaneous tiltmeter functionality, offering a broad detection range (-90o to 90o) with high precision (0.05o), a rapid reaction time (0.11 s), and enhanced durability. Moreover, a seamless integration has enabled water wave detection, language programming and human limb monitoring. Especially, the integration of tiltmeter and a 3D motion platform results in a surface structure scanning system capable of effectively performing large area (＞200 cm2) and height difference scanning functions. This innovative approach holds great potential for transformative changes in the fields of advanced manufacturing, flexible robotics, and the flexible sensing, further facilitating widespread adoption.
