An international team led by researchers from the Universitat Rovira i Virgili (URV) has developed an intelligent device capable of monitoring the temperature of the skin continuously and accurately.
The device uses a thermoelectric system that works without batteries or an external power supply to detect temperature variations associated with inflammation and infection. Based on a flexible, self-sustaining thermoelectric system, this device can monitor wounds and lesions. The results of the project have been published in the journal Advanced Science.
The device is able to precisely measure small changes in temperature and to identify specific points of inflammation thanks to its structure, which is based on a network of thermocouples. These are unions of semiconductor materials that generate an electrical signal when they detect differences in temperature.
The system can display a colour map with temperature gradients, and this means that, without needing to be trained, healthcare staff can quickly identify the affected areas.
