AI Technical Summary
Existing wirelessly powered optogenetic systems suffer from difficulties in assembly, low integration, slow response speed, and poor control precision. Furthermore, traditional power supply methods restrict the free behavior and ecological validity of experimental animals.
A μ-LED optogenetic neural probe based on energy module regulation is used. The μ-LED excitation source and energy module array are connected by a flexible substrate and metal wires. The probe is powered by photoelectric conversion through external light energy. Photonic devices are integrated to perform regional collimation and light stimulation at specific depths. A GaN-based multi-quantum-well structure and a flexible substrate are used to achieve wireless power supply and high spatial resolution stimulation.
It enables high spatial resolution multiple access stimulation powered wirelessly, eliminating the need for animal restraint, thus increasing experimental freedom and the diversity of data acquisition, reducing the suffering of experimental subjects, and supporting long-term, fully wireless neuromodulation.
