We present a design for wireless power transfer, via inductively coupled coils, to a spinning disk. The rectified and stabilised power feeds an Arduino-compatible microcontroller (μC) on the disc, which in turn drives and monitors various sensors and actuators. The platform, which has been conceived to flexibly prototype such systems, demonstrates the feasibility of a wireless power supply and the use of a μC circuit, for example for Lab-on-a-disk applications, thereby eliminating the need for cumbersome slip rings or batteries, and adding a cogent and new degree of freedom to the setup. The large number of sensors and actuators included demonstrate that a wide range of physical parameters can be easily monitored and altered. All devices are connected to the μC via an I(2)C bus, therefore can be easily exchanged or augmented by other devices in order to perform a specific task on the disk. The wireless power supply takes up little additional physical space and should work in conjunction with most existing Lab-on-a-disk platforms as a straightforward add-on, since it does not require modification of the rotation axis and can be readily adapted to specific geometrical requirements.
我们提出了一种通过感应耦合线圈向旋转磁盘进行无线功率传输的设计方案。经整流和稳压后的功率为磁盘上的 Arduino 兼容微控制器 (μC) 供电，μC 反过来驱动和监控各种传感器和执行器。该平台旨在灵活地对这类系统进行原型设计，展示了无线供电和使用 μC 电路的可行性，例如用于磁盘上实验室 (Lab-on-a-disk) 应用，从而消除了对繁琐滑环或电池的需求，并为设置增加了一个有力且新颖的自由度。所包括的大量传感器和执行器表明，可以轻松监测和改变广泛的物理参数。所有设备都通过 I(2)C 总线连接到 μC，因此可以通过其他设备轻松交换或扩充，以便在磁盘上执行特定任务。无线电源占用的额外物理空间很小，并且应该可以与大多数现有的磁盘上实验室平台配合使用，作为简单的附加组件，因为它不需要修改旋转轴，并且可以轻松适应特定的几何要求。
