传感器可以分析材料的表面，利用其会产生的阻力来决定自己所用力道。
Sensors can analyse the surface of materials and, using the amount of resistance they show, work out the force to apply to an object.
它们拥有很有趣的特点，例如导热性差(可以做很好的隔热材料)，以及低阻力(意味着表面很滑)。
They often have interesting properties, such as poor heat conductivity (which makes them good insulators) and low friction (which makes them slippery).
