We have designed and constructed a wearable device for skin-contact thermography [Giansanti D, Maccioni G. Development and testing of a wearable integrated thermometer sensor for skin-contact thermography. Med Eng Phys 2007;29(5):556-65] that uses 16 integrated silicon sensors with a thermal resolution of 0.03 degrees C and a spatial resolution of 1.6 x 10(-5)m(2). In order to perform a dynamic bench test, a thermographic phantom was designed and constructed that permits the imposition of 16 independent thermal waveforms to the device. The phantom was based on 16 small black bodies units designed with a 10(-4) m thin layer of black conductive gum. An infrared system was used in closed loop to correct in real time the error between the theoretical and the actual temperature imposed. The methodology proved to be adequate for bench testing the device. The difference between the imposed and the theoretical waveforms was never greater than 0.85 x 10(-2) degrees C in mean value, as measured with the infrared (IR) system.
我们设计并构建了一种用于皮肤接触热成像的可穿戴设备[吉安桑蒂 D，马乔尼 G。用于皮肤接触热成像的可穿戴集成温度计传感器的开发与测试。《医学工程与物理学》2007 年；29(5)：556 - 65]，该设备使用 16 个集成硅传感器，热分辨率为 0.03 摄氏度，空间分辨率为 1.6×10⁻⁵ 平方米。为了进行动态台架测试，设计并构建了一个热成像模型，该模型允许对设备施加 16 个独立的热波形。该模型基于 16 个小黑体单元，这些单元由一层 10⁻⁴ 米厚的黑色导电胶设计而成。使用一个红外系统进行闭环操作，以实时校正理论温度与实际施加温度之间的误差。该方法被证明适用于对设备进行台架测试。用红外（IR）系统测量时，施加波形与理论波形之间的差值平均值从未大于 0.85×10⁻² 摄氏度。
