Abstract：

High conductivity, high mechanical flexibility/stretchabbility and even self adhesiveness are required for conductors in the areas of flexible and wearable electronics. However, conventional conductors like metals and inorganic semiconductors have very limited flexibility and stretchability, and they are not self-adhesive. Conducting polymers like PEDOT:PSS can have high mechanical flexibility, but they have limited stretchability and they are not self-adhesive. Here, I will present some of our results on developing highly conductive, highly stretchable and self-adhesive conducting polymers. We also demonstrated their applications, including flexible transparent electrodes of optoelectronic devices like organic solar cells and perovskite solar cells, compliant dry electrodes of soft robots and dry electrodes for the detection of epidermal biopotential signals including electrocardiogram (ECG), electromyogram (EMG) and electroencephalogram (EEG). Because they can always form conformal contact to skin and detect high-quality biopotential signals even during body movement, they can be used for continuous healthcare monitoring for long terms.
