The invention discloses a multi-mode sensing feedback patch and a manufacturing method thereof, and belongs to the technical field of motion capture. The multi-mode sensing feedback patch comprises a substrate. The substrate is made of a flexible material. The substrate has a first surface on which a strain sensing layer and a thermal feedback layer are disposed. Wherein the strain sensing layer is used for detecting the stretching state of human body muscles, and the thermal feedback layer is suitable for being connected with current to generate Joule heat so as to achieve thermal feedback. The first surface of the substrate is also provided with a packaging layer. The strain sensing layer and the thermal feedback layer are located between the encapsulation layer and the substrate. Furthermore, the packaging layer is also made of a flexible material, and packaging of the strain sensing layer and the thermal feedback layer can be realized through the packaging layer. A myoelectricity acquisition layer is arranged on one side, away from the substrate, of the packaging layer, and the myoelectricity acquisition layer is used for being in contact with human skin to perform myoelectricity acquisition. And the myoelectricity acquisition layer realizes electrical isolation and physical space decoupling with the strain sensing layer and the thermal feedback layer through the packaging layer.

This invention discloses a GaN power amplifier system and control method based on envelope tracking and thermal feedback. The system includes a system control module, and an audio signal conditioning module, a programmable power supply module, a thermal feedback module, and a GaN power output module, all communicatively connected to the control module. The system control module executes dual closed-loop control logic: the first closed loop dynamically adjusts the output voltage of the programmable power supply module using envelope tracking technology, ensuring it closely follows changes in the amplitude of the audio signal, thus reducing power consumption and heat generation at the source; the second closed loop, based on real-time temperature data collected by the thermal feedback module, prioritizes dynamic compression of the low-frequency band of the audio signal or smoothly reduces the overall main volume when overheating occurs, achieving intelligent thermal derating protection without interrupting playback. This invention significantly improves the energy efficiency and reliability of the power amplifier system.
