Bioinspired electronics are rapidly promoting advances in artificial intelligence. Emerging AI applications, e.g., autopilot and robotics, increasingly spur the development of power devices with new forms. Here, we present a strain-controlled power device that can directly modulate the output power responses to external strain at a rapid speed, as inspired by human reflex. By using the cantilever-structured AlGaN/AlN/GaN-based high electron mobility transistor, the device can control significant output power modulation (2.30-2.72 × 103 W cm-2) with weak mechanical stimuli (0-16 mN) at a gate bias of 1 V. We further demonstrate the acceleration-feedback-controlled power application, and prove that the output power can be effectively adjusted at real-time in response to acceleration changes, i.e., ▵P of 72.78-132.89 W cm-2 at an acceleration of 1-5 G at a supply voltage of 15 V. Looking forward, the device will have great significance in a wide range of AI applications, including autopilot, robotics, and human-machine interfaces.

受人体反射启发的应变控制动力设备。

受生物启发的电子产品正在迅速推动人工智能的发展。新兴的AI应用程序，例如自动驾驶仪和机器人技术，越来越以新的形式刺激着动力设备的发展。在这里，我们介绍了一种应变控制的功率设备，它可以直接调制输出功率对外部应变的快速响应，这是受到人体反射的启发。通过使用悬臂结构的AlGaN / AlN / GaN基高电子迁移率晶体管，该器件可以在栅极处具有较弱的机械刺激（0-16 mN）的情况下，控制明显的输出功率调制（2.30-2.72×103 W cm-2）。偏置电压为1V。我们进一步演示了加速度反馈控制的电源应用，并证明了可以根据加速度变化实时有效地调节输出功率，即▵P为72.78-132。
