Cover Story: Due to the abundant functional groups and high sensitivity to molecules, GO is a common material for moisture–electricity generators (MEGs). However, existing devices primarily focus on constructing complex gradients and increasing voltage, often overlooking the critical roles of response and recovery times. We designed a low-cost, highly flexible, lightweight MEG; a 0.6 cm2 device can generate 69 mV in 2.4 s. Notably, higher output voltages can be easily achieved by connecting multiple MEG units in series. The gradient of GO functional groups was easily created using a simple drop-casting method. As the transition layers, rGO/Ag enhanced cycling stability and shortened recovery time. This study proposes applications for MEG in humidity sensing and wearable electronics. View this paper
