持续健康监测对于临床护理至关重要，尤其是对于新生儿和儿科重症监护病房的患者。目前的监测需要用强力粘合剂将有线生物传感器固定在皮肤上，这可能在移除过程中引起刺激和医源性损伤。新兴的无线替代品很有吸引力，但对皮肤粘合剂的要求仍然存在。在这里，我们提出了一种材料策略，使无线触发降低粘合强度，以消除在拆除过程中受伤的可能性。这些材料包括硅树脂复合材料，其中含有可结晶的油，其熔化温度接近但高于表面体温。这种固/液相转变在加热时发生，使皮肤界面处的粘附力降低75%以上。实验和计算研究揭示了石油随机混合和图案确定性的复合材料的影响的见解。包括无线控制加热和减少粘连的皮肤集成传感器的演示说明了这些想法在临床级健康监测中的广泛用途。可切换的粘合剂有助于从脆弱的皮肤上安全地移除可穿戴健康监测设备。
Continuous health monitoring is essential for clinical care, especially for patients in neonatal and pediatric intensive care units. Monitoring currently requires wired biosensors affixed to the skin with strong adhesives that can cause irritation and iatrogenic injuries during removal. Emerging wireless alternatives are attractive, but requirements for skin adhesives remain. Here, we present a materials strategy enabling wirelessly triggered reductions in adhesive strength to eliminate the possibility for injury during removal. The materials involve silicone composites loaded with crystallizable oils with melting temperatures close to, but above, surface body temperature. This solid/liquid phase transition occurs upon heating, reducing the adhesion at the skin interface by more than 75%. Experimental and computational studies reveal insights into effects of oil mixed randomly and patterned deterministically into the composite. Demonstrations in skin-integrated sensors that include wirelessly controlled heating and adhesion reduction illustrate the broad utility of these ideas in clinical-grade health monitoring. Switchable adhesives facilitate safe removal of wearable health monitoring devices from fragile skin.
