(2015, September 28). In this research, a high-resolution process is developed to fabricate high-quality stretchable sensor networks with sensors, dielectrics, electrodes, and switching devices based on spin-coated-on polyimide. The substrate contains an array of microscale pyramidal features, and the electrode comprises a polymer composite. Some of the latest research is from Purdue University, where researchers have developed a new type of soft and stretchable In this paper, a new type of highly stretchable strain sensor was developed to measure large strains. Fig. Soft sensors are typically composed of a deformable con-ducting material patterned onto, attached to, or encapsulated within an inactive stretchable material.

In this work, Traditional printing methods are used for fabrication of stretchable and wearable sensors which can be mounted on the human skin for the purpose of health tracking. In a similar fashion, inkjet printing techniques have been used to fabricate various flexible/stretchable resistive and capacitive sensors. I’m hoping this will allow to make super simple stretch sensors and lead to other interesting possibilities. Steele, & W.
