Fabrication of Silver-Nanowire/PVDF Self-Supporting Thin Flexible Electrode Membranes

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 thin polymer membranes can be produced at large scale. We have compared different up-scalable techniques electrode based on PVDF a function silver nanowire concentration, using electrospinning, spincoating, drop-casting techniques. The films were investigated by four-point probing, optical microscopy, atomic force well stability tests bending, water exposure. show, that combination electrospinning spin-coating presents reliable method AgNW-PVDF nanofiber membrane (NMEs). Our (NMEs) exhibit 10 times lower sheet resistance than film (TFEs) comparisons spincoating same amounts AgNWs. Upon immersion up 48 hours, we do not detect any release decomposition fabricated electrodes, which is view composite humid environment.
