海胆脊柱在水流中产生电力,激发了一种新的自力水下传感器。 Sea urchin spines generate electricity in water flow, inspiring a new self-powered underwater sensor.

Wang Zuankai教授领导的研究人员发现,由于梯度多孔结构使机械电能感测成为可能,海胆脊在暴露于水流时产生高达100毫伏的电信号。 Researchers led by Prof. Wang Zuankai have discovered that sea urchin spines generate electrical signals up to 100 millivolts when exposed to water flow, thanks to a gradient porous structure that enables mechanoelectrical sensing. 这一物理机制即使在死脊上也活跃,它激励团队创建了3D打印的生物感应器,其电压是非梯度设计的三倍,振幅是非梯度设计的八倍。 This physical mechanism, active even in dead spines, inspired the team to create a 3D-printed bionic sensor with three times higher voltage and eight times greater amplitude than non-gradient designs. 这些单元中的3x3阵列展示了实时、自力水下流动探测,精确定位,为深海监测、基础设施遥感、航空航天和脑计算机接口提供了潜力。 A 3x3 array of these units demonstrated real-time, self-powered underwater flow detection with precise localization, offering potential for deep-sea monitoring, infrastructure sensing, aerospace, and brain-computer interfaces.
