Flexible electrodes play an increasing role for medical applications, such as ECG (electrocardiography) or TENS (Transcutaneous electrical nerve stimulation) due to comfort in use and thus their suitability health monitoring under movement during sport. Polymers, polyvinylidene fluoride (PVDF), are promising the development of fabrication methods materials application cases, stable flexible thi...

The photo-rechargeable supercapacitor enables the self-powering of flexible wearable electronics. However, electronics require supercapacitors not only with excellent flexibility but also high energy density. P-diaminoazobenzene (P-Azo) as a new type organic electrode material NN is directly connected to benzene ring and forms large π-conjugated system, which makes it have lower lowest unoccup...

Perovskite solar cells (PSCs) are attracting widespread attention due to their exceptional photovoltaic performance and potential for large-scale production via low-cost, high-throughput roll-to-roll (R2R) methods. Full realization of this approach requires replacement the evaporated metal electrode commonly used in PSCs. Here, a novel vacuum-free R2R-compatible method is introduced fabricate d...

Flexible Supercapacitors In article number 2205708, Lunhui Guan and co-workers fabricate a mechanically stable all flexible supercapacitor by in-situ electrode growth. The device presents electrochemical property with device-level fracture fatigue resistance. This versatile its integrated functional units can be employed as sensor system under harsh environments.
