从交通安全的角度来看，迫切需要配备应变传感器的智能轮胎作为道路状况的警告系统，并在恶劣的路面上优化制动控制。然而，由于传统的箔应变片具有高刚度，它会导致分析区域的行为不自然。本研究提出了一种新型的橡胶基应变传感器制作使用光刻。橡胶基底具有与轮胎表面相同的机械性能：因此传感器不会干扰轮胎变形，可以准确监测轮胎的行为。本研究详细介绍了橡胶基传感器的设计和制造。为了验证，传感器连接到梁试样，并发现具有超过1013的疲劳寿命和高达14%的可测量应变范围。将该传感器应用于市售汽车轮胎，发现其成功地测量了轮胎的应变。(C)2008 Elsevier B.V.保留所有权利。
From a traffic safety point-of-view, there is an urgent need for intelligent tires equipped with strain sensors as a warning system for road conditions and for optimized braking control on poor road surfaces. However, since a conventional foil strain gage has high stiffness, it causes the analyzed region to behave unnaturally. The present study proposes a novel rubber-based strain sensor fabricated using photolithography. The rubber base has the same mechanical properties as the tire surface: thereby the sensor does not interfere with the tire deformation and can accurately monitor the behavior of the tire. This investigation details the design and manufacture of the rubber-based sensor. For verification, the sensor was attached to a beam specimen and found to have a fatigue life of over 1013 and a measurable strain range up to 14%. The sensor was applied to a commercially available automobile tire and found to successfully measure the strain of the tire. (C) 2008 Elsevier B.V. All rights reserved.
