Wearable Device for Skin Contact Thermography: Design, Construction and Testing

摘要

The need for wearable devices for thermal monitoring is rising. These devices could be used to continuously monitor patients for breast cancer investigation or vascular, dermatological and rheumatic disorders, in viability studies, or during physical exercise. We designed and constructed a wearable device for skin-contact thermography that uses integrated silicon sensors. The device was validated using a phantom with a dynamic bench test. The thermal resolution was greater than 0.03DGC, and the spatial resolution was equal to 1.6OE10-5 m2. We also investigated the devices performance on five clinical subjects. Results of these studies showed a maximal error of less than 0.1DGC in each evaluation.
