In article number 2100956, Haitao Zhang, Weiqing Yang, Jun Chen, and co-workers invent a low-cost, scalable, air-stable conducting polymer ink via facile assemble-disperse strategy for printed micro-supercapacitors, which exhibits remarkable energy storage capacity as power source wearable bioelectronics in the era of Internet Things.

Organic bioelectronics involves the connection of organic semiconductors with living organisms, organs, tissues, cells, membranes, proteins, and even small molecules. In recent years, this field has received great interest due to development all kinds devices architectures, enabling detection several relevant biomarkers, stimulation sensing cells recording electrophysiological signals, among ot...

Organic Electrochemical Transistors Among other merits, the ability of organic electrochemical transistors to form an intimate interface with a biological environment, enabling efficient ion-to-electron transduction, makes them particularly desirable for operation within living organism (in vivo). In article number 2101874, Ali Nawaz, Prashant Sonar, and co-workers comprehensively review wide r...

E-Tattoos In article number 2204159, Hyung-Ryong Kim, Jae-Woong Jeong, Steve Park, and co-workers introduce a new class of e-tattoo that can be implemented on-the-fly according to users' demands. To realize intimate, compact, rapid assembly intrinsically conductive durable EGaIn composites, ethanol-based ink is developed. Demonstrations wearable bioelectronics confirm the validity in healthcare.
