The latest breakthrough in the field of oncology! New wearable devices monitor tumor size in real time

Evaluating the effectiveness of cancer treatment is a key issue, and tools that can monitor changes in tumor size in real time are key to

Using electronic materials, the researchers designed a wearable strain sensor that can measure and record changes in

The FAST sensor is made by depositing a 50 nm gold layer on top of the styrene-ethylene-butene-styrene drip casting layer, which is prone to expansion or contraction as the tumor progresses

Custom-designed printed circuit boards and mobile applications for this sensor enable real-time and historical sensor readings at the push of a

To verify its ability to discern shape-volume changes in vitro, the researchers measured the output of the sensor when placed on top of a 3D printed model tumor, and they found that the sensor recorded significant changes

Subsequently, the researchers once again verified the accuracy and effectiveness of the sensor in measuring changes in tumor volume in vivo

Next, the researchers also used erlotinib as an example to evaluate how the FAST sensor measured the volume of tumors in mice during treatment

Finally, the researchers used experimental immunotherapy to perform sensor characterization of Balb/c mice's A20B cell lymphoma solid tumor model to demonstrate the accuracy and effectiveness of sensor monitoring in multiple tumor models and treatment modalities

In this regard, the researchers said that the miniature device they designed this time, the flexible autonomous sensor (FAST) that measures tumors, represents a new, fast, cheap, portable and accurate way to
