With the approach, the researchers — who are based at Stanford University and Tianjin University — create a stretchable 527-stage ring oscillator consisting of 1,056 transistors and 528 logic gates with operation speeds of 1 MHz, as well as an active-matrix tactile sensor array that can recognize braille. The sensor density of 2,500 units per cm² is 10 times higher than the density of mechanical receptors in a human fingertip. Bao and colleagues also used their transistors to access and drive individual pixels of a 10 × 20 light-emitting diode (LED) matrix display that can conformally adhere to a human finger and has a refresh rate of 60 Hz. The LEDs can also maintain a stable brightness under mechanical deformation.

通过这种方法，来自斯坦福大学和天津大学的研究人员创建了一个可拉伸的 527 级环形振荡器，由 1,056 个晶体管和 528 个逻辑门组成，运行速度为 1 MHz，以及一个有源矩阵触觉传感器阵列可以识别盲文。传感器密度为 2,500 个单位/cm ²，比人类指尖机械感受器的密度高 10 倍。 Bao 和同事还使用他们的晶体管来访问和驱动 10 × 20 发光二极管 (LED) 矩阵显示器的各个像素，该显示器可以保形地粘附在人类手指上，并且刷新率为 60 Hz。 LED在机械变形下也能保持稳定的亮度。
