The hierarchical architecture comprises a hydrophilic cotton layer, an electrospun polyurethane (PU) adhesive interlayer, and a hydrophobic PU/ethylcellulose (EP) layer, where the interlayer serves as the critical regulator of liquid behavior. By tuning the porosity to range from 36.3 % to less than 1 % through controlling the electrospinning duration of the PU adhesive layer (30–90 min) and hot-pressing temperature (60–80 °C), we achieved synergistic bidirectional fluid control: efficient exudate drainage performance coupled with controllable backflow propensity. Specifically, the water droplets penetrated from the hydrophobic to the hydrophilic side within 7 s, and additionally, larger porosity correlated with enhanced backflow, thereby achieving balanced moisture retention. Systematic <em>in vitro</em> investigations revealed correlations between fabrication parameters and the membrane's morphological, wettability, air permeability (73.0 to 3.3 mm/s), and liquid management properties. Moreover, the trilayered composite membrane possessed great cytocompatibility (approximately 99 %) and maintained skin humidity above 44 %.

Flexible detection devices have attracted increasing attention in recent years and are expected to continue to grow over the next decade due to their advantages in terms of user compliance for long term monitoring, improved skin-device coupling and the ability to develop low-cost and recyclable devices. Several of those sensing devices are based on the piezoresistive effect which have been used to monitor heart pulse, respiratory rate, and blood pressure, among others. Typically, these sensors are based on synthetic polymer, though the related environmental concerns are promoting their replacement by natural polymers, allowing to reduce waste and electronic waste (e-waste) accumulation in landfills and oceans, as well as the presence of microplastics. Thus, the main goal is incorporating flexible natural polymers that can replicate or even improve the properties of traditional synthetic materials while offering advantages such as non-toxicity, biocompatibility, durability, and biodegradability.
