应变不敏感的可穿戴传感器由于其高精度感测而不受身体运动（诸如弯曲、伸展和扭转运动）的影响而获得了大量关注。这项工作报告集成，应变不敏感的pH值和温度传感器上制作的双轴可拉伸kirigami结构定量测量汗液pH值水平和体温。值得注意的是，pH和温度传感器在施加高达220%的双轴拉伸应变和高达360°的扭转应变下表现出令人印象深刻的应变不变响应。通过描绘具有成本效益的制造，灵活的kirigami结构，透气缺口，高线性度的响应和皮肤贴合性的优秀组合，我们的设备将在皮肤启发的可穿戴传感器的应用中开辟一条有前途的新路线。
Strain-insensitive wearable sensors have garnered substantial attention owing to their high precision sensing irrespective of body movements such as bending, stretching, and twisting motions. This work reports integrated, strain-insensitive pH and temperature sensors fabricated on a biaxially stretchable kirigami structure to quantitively measure the sweat pH levels and body temperature. Notably, an impressive strain-invariant response was demonstrated by the pH and temperature sensors under an applied biaxial tensile strain up to 220% and torsional strain up to 360°. By depicting an excellent combination of cost-effective fabrication, flexible kirigami structure, breathable notches, high linearity of response, and skin conformity, our device will open a promising new route in the application of skin-inspired wearable sensors.
