本文提出了一种用于光遗传学刺激的智能EnergeCage-homecage（HC）系统，该系统配备了基于磁共振的无线功率传输（WPT），闭环功率控制和通过蓝牙低功耗（BLE）进行数据通信。拟议的系统由四个矩形倾斜重叠高Q谐振器和一个绕线驱动线圈组成，全部调谐在13.56 MHz。实现了一种光学头台，能够基于通过BLE链路实时接收的刺激命令驱动4个微型发光二极管（μ-LED），同时以闭环方式无线供电。测量结果表明，整个头台单元在整个家庭住宅中提供高达51 mW的功率，最大高度为10 cm，而发射机（Tx）的功耗从1.5 W变为2.1 W（总η，2.4-3.4%）。
This paper presents a smart EnerCage-homecage (HC) system for optogenetic stimulation, equipped with magnetic resonance based wireless power transmission (WPT), closed-loop power control, and data communication via Bluetooth Low Energy (BLE). The proposed system is encompassed with four rectangular slanted overlapping high-Q resonators and a wire-wound driver coil, all tuned at 13.56 MHz. An optical headstage is implemented capable of driving 4 micro light-emitting diodes (μ-LEDs) based on stimulation commands received via the BLE link on-the-fly, while being wirelessly powered in a closed-loop fashion. Measurements show that the entire headstage unit was provided with up to 51 mW throughout the homecage up to the maximum elevation of 10 cm, while the transmitter (Tx) power consumption changed from 1.5 W to 2.1 W (overall η, 2.4-3.4%).
