为解决机器人辅助血管内手术中缺乏触觉反馈的难题，研究人员开发了一种基于铁磁流体（ferrofluid）的触觉引导系统。该系统通过磁场调控铁磁流体黏度变化，模拟血管内器械接触力，实验证实其可提供方向性触觉反馈（感知准确率44%），为提升手术安全性和操作直觉性提供了新思路。

The ferrofluid used was a cheap, commercially available formulation based on mineral oil and magnetite nanoparticles,” says Koser, explaining just how simply their device was built. Chain reactions.

In 2019 [Simen] and [Amud], two students from the University of Oslo, set out to design a unique open-source display. The result was Fetch, a display that uses electromagnets to suspend ferrofluid … ...

Ferrofluid is a magnetic liquid, invented by a NASA engineer in the 1960s, that has, in recent years, become a popular medium among scientifically inclined artists. Ferroflow is an interactive ...

Ferrofluid is a liquid that can be attracted to magnets and is made out of iron oxide particles suspended in a carrier fluid. Sample of microplastic collected by Oregon State University.
