The developing fields of wearable electronics and soft robotics have created a strong demand for flexible and stretchable strain sensors. This work presents a printing technique and conductive multiwalled carbon nanotube/silicone polymer nanocomposites applied to achieve embedded piezoresistive large strain sensors. A printing process that allows the sensors to be produced inside a silicone substrate...
A model, which takes into account the indentation size effect, was proposed to relate hardness and its standard deviation to the quality of the sample surface, i.e., the roughness and the tilt. Stainless steel samples were mechanically polished so as to obtain various roughness and tilt. Then the quality of the surface and the hardness were measured respectively by scanning probe microscopy and by...
