Examples of Flexible Transistor
Flexible transistors have shown great potential for various applications in the real world. Here are three examples:
Wearable Technology: Flexible transistors are used in wearable electronic devices, such as smartwatches, fitness trackers, and health monitoring devices. These devices need to be lightweight, comfortable to wear, and must conform to the shape of the human body. Flexible transistors can help achieve these requirements, as they can be built on flexible substrates, enabling the device to bend and flex without affecting its performance.
Flexible Displays: Flexible transistors have enabled the development of flexible displays that can bend, fold, or roll up. This is particularly useful for creating devices with large displays, such as smartphones and tablets, that can be easily carried around or stored. Samsung’s foldable smartphones, including the Galaxy Fold and Galaxy Z Flip series, are examples of products that employ flexible transistors in their foldable AMOLED screens.
E-Skin: Electronic skin (E-skin), is a flexible, stretchable, and touch-sensitive material that resembles real human skin. Flexible transistors are a key component in E-skin, enabling it to process touch input, and being lightweight and adaptable to various shapes without being rigid. E-skin is useful for applications such as robotics, prosthetics, and wearable computing, providing touch sensitivity, temperature sensing capabilities, and other sensing functionalities.
