A new smart skin patch can detect infections in real time without the need for batteries, offering a potential advancement in wound monitoring and personalized medicine. The flexible sensor adapts to the skin and can be worn for several days, according to researchers.
How it effectively works: Thermoelectric Technology
An international research team has developed the device, which continuously and precisely monitors skin temperature using a thermoelectric system. This system eliminates the need for batteries or an external power source, rather detecting temperature variations associated with inflammation and infections.
The findings were published in the journal Advanced Science.
The project was a collaborative effort, involving researchers at the University of porto, who specialize in energy recovery systems. The initial goal was to increase the autonomy of sensors used in medical and industrial settings.
Eduard Llobet, a researcher, stated that the aim was to “avoid battery addiction and create flexible devices that can be adapted to the skin or other areas.”
The Importance of Temperature Monitoring
Temperature is a key indicator for the early diagnosis of wounds and inflammatory processes. Local temperature changes can signal infections, healing complications, or other pathological changes. Conventional methods, such as infrared cameras or spot sensors, often require patient immobilization and cannot monitor the entire skin surface.
Creating a Thermal Skin Map
The device accurately measures small temperature changes and identifies specific inflammation points using a network of thermocouples. These thermocouples,combinations of semiconductor materials,generate an electrical signal when detecting temperature differences.
Llobet explained,”It is as if we create a thermal skin map,with points indicating the affected areas.”
Rigorous testing and Validation
The device has undergone validation through numerical simulations and experimental tests on human skin, including tests simulating sweat conditions using saline. Results showed the sensor could detect temperature variations as small as 0.4 degrees Celsius and react in less than 3 seconds, allowing for real-time monitoring of wound evolution and rapid identification of infection signs.
flexible and Durable Design
the device is constructed from flexible thermoelectric materials combined with a conductive polymer, printed using techniques similar to those used in shirt printing. This allows for manufacturing on flexible polymeric substrates that easily conform to the skin.
According to researchers, this configuration is not only more precise than traditional sensors but also more resistant to external interference, such as sweating or skin movement.
The device’s durability was also tested.The mechanical engineering department subjected the sensors to hundreds of bending cycles to assess long-term deterioration. Silvia from Flor, head of the department, noted that the sensor retained its functionality even after repeated deformations.
Easy-to-Interpret Data
The information provided by the sensor is designed for easy interpretation.Llobet explained that the system can display a color map with a temperature gradient, enabling medical staff to quickly identify affected areas without extensive training. This facilitates clinical decision-making and proactive patient health management.
Future applications
The sensor can be worn for several days before needing replacement, similar to conventional techniques. Flor stated that the goal is for the sensor to be worn comfortably, like any other device. This technological advancement paves the way for more personalized and accessible medicine.
Beyond preventing infections in surgical wounds, the sensor can be adapted for monitoring inflammatory processes or integrated into medical kits. The research team is currently working on new projects to expand the device’s functionalities, including integrating biosensors to measure other physiological variables, such as dissolved gas levels or specific biomarkers.
Researchers concluded that they intend to continue developing the technology to make it even more versatile and useful in clinical settings.
