“After addressing the stretchability and assembly issues, we had to tackle the problems that come with working with wearable electronics in high humidity and under rapid growth rates,” Wang said. “We needed reproducible results so we could not have the sensors fall off or electronically fail during the growth experiments. We finally came up with a seamless electrode and interface that was not affected by the demanding conditions.”
The “Stretchable-Polymer-Electronics-based Autonomous Remote Strain Sensor,” or SPEARS2—is the product of three years of hard work, proving that applied science rarely experiences eureka moments.
