A fundamental approach to fabricating silicone‐based adhesives with highly tunable adhesion force for the skin‐contact applications is presented. Liquid blends consisting of vinyl‐multifunctional polydimethylsiloxane (V‐PDMS), hydride‐terminated PDMS (H‐PDMS), and a tackifier composed of a silanol‐terminated PDMS/MQ resin mixture and the MQ resin are used as the adhesive materials. The peel adhesion force of addition‐cured adhesives on the skin is increased by increasing the H‐PDMS molecular weights and the tackifier content, and decreasing the H‐PDMS/V‐PDMS ratio. There is an inverse relationship between the adhesion force and the Young's modulus. The low‐modulus adhesives with a low H‐PDMS/V‐PDMS ratio exhibit enhanced adhesion properties. The low‐modulus adhesives with the high MQ resin content show significantly enhanced adhesion properties. These adhesives exhibit a wide range of modulus (2–499 kPa), and their adhesion force (0.04–5.38 N) is superior to commercially available soft silicone adhesives (0.82–2.79 N). The strong adhesives (>≈2 N) provide sufficient adhesion for fixing the flexible electrocardiogram (ECG) device to the skin in most daily activity. The human ECG signals are successfully recorded in real time. These results suggest that the silicone‐based adhesives should be useful as an atraumatic adhesive for the skin‐contact applications.

具有高度可调粘合力的有机硅基胶粘剂，用于皮肤接触应用

提出了一种用于皮肤接触应用的具有高度可调的粘合力的有机硅粘合剂的基本制造方法。由乙烯基多官能聚二甲基硅氧烷（V-PDMS），氢化物封端的PDMS（H-PDMS）和由硅烷醇封端的PDMS / MQ树脂混合物与MQ树脂组成的增粘剂组成的液体共混物用作粘合剂材料。通过增加H-PDMS分子量和增粘剂含量，并降低H-PDMS / V-PDMS比，可以增加加成固化粘合剂在皮肤上的剥离粘合力。粘附力与杨氏模量之间存在反比关系。H-PDMS / V-PDMS比低的低模量粘合剂表现出增强的粘合性能。MQ树脂含量高的低模量粘合剂表现出显着增强的粘合性能。这些胶粘剂的模量范围很广（2–499 kPa），其粘着力（0.04–5.38 N）优于市售的柔软有机硅胶粘剂（0.82–2.79 N）。坚固的粘合剂（>≈2N）可提供足够的粘合力，以在大多数日常活动中将柔性心电图（ECG）设备固定在皮肤上。人类心电图信号可以实时成功记录。这些结果表明，有机硅基胶粘剂应作为皮肤接触应用的无创伤胶粘剂。≈2 N）可提供足够的粘附力，以在大多数日常活动中将柔性心电图（ECG）设备固定在皮肤上。人类心电图信号可以实时成功记录。这些结果表明，有机硅基胶粘剂应作为皮肤接触应用的无创伤胶粘剂。≈2 N）可提供足够的粘附力，以在大多数日常活动中将柔性心电图（ECG）设备固定在皮肤上。人类心电图信号可以实时成功记录。这些结果表明，有机硅基胶粘剂应作为皮肤接触应用的无创伤胶粘剂。
