The emergence of flexible and stretchable electronic components expands the range of applications of electronic devices. Flexible devices are ideally suited for electronic biointerfaces because of mechanically permissive structures that conform to curvilinear structures found in native tissue. Most electronic materials used in these applications exhibit elastic moduli on the order of 0.1-1 MPa....

The inner walls of fused silica micro-capillaries were successfully coated with polyaniline nanofibres using the "grafting" approach. The optical response of polyaniline coatings was evaluated during the subsequent redoping-dedoping processes with hydrochloric acid and ammonia solutions, respectively, that were passed inside the micro-capillary in continuous flow. The optical absorbance of the ...
