Developed Wearable Sensor That Can Be Applied To Skin At Room Temperature


Scientists have developed a wearable sensor that can be applied directly on human skin. The sensor, which has a different production process than its counterparts, is critical for instant data tracking. Experts say that this sensor was washed and cleaned.

Scientists working at Penn State University in the US have been able to develop wearable sensors that can be applied directly on the skin. These sensors allow the measurement of heart rate and pulse, body temperature, and the amount of oxygen in the blood that medical devices do today. In addition, a person can clean these sensors that look like tattoos on their body by washing them with hot water.

At the heart of wearable sensors lies flexible circuit board manufacturing technologies. In fact, scientists have been working on such circuit boards for some time. The latest wearable sensor produced takes existing technologies several steps further. Because scientists have managed to create a solution to one of the most important problems of flexible circuit boards with their work.

Here's what scientists ' latest discovery looks like

Flexible circuit boards, although they have several advantages, go through a demanding manufacturing process. For example, the connections of these circuit boards occur at about 300 degrees Celsius. In this case, it was not possible for such a circuit to be performed on the human body. But scientists have managed to create an auxiliary layer that allows the metal layers to connect to each other. This layer allows the circuit printed on the human body to become operational under a safe temperature value.

The scientists ' auxiliary layers are made up of a combination of calcium carbonate and polyvinyl alcohol paste found in peelable face masks and eggshells. Scientists also attach the circuit they press directly on this layer to the surface of the skin through an air gun, and they can make the necessary adjustments.

By making the wearable sensor applicable to human skin, scientists say this type of sensor is crucial for instant data tracking. Scientists who say that the sensor does not lose its electrochemical structure after application emphasize that this type of material also has no harm to the skin, especially that it can be used smoothly even in people with sensitive skin, such as infants and the elderly. Another point that scientists are focusing on is that this wearable sensor does not give patients extra weight. Experts are continuing their work on the wearable sensors they have developed.
