The present disclosure provides an adaptive conditioning circuit supporting ultrasonic-vibration fusion, and a flexible module. The adaptive conditioning circuit supporting ultrasonic-vibration fusion includes a front-end conditioning unit, a vibration conditioning unit, an ultrasonic conditioning unit, and a microcontroller unit, MCU, where the vibration conditioning unit and the ultrasonic conditioning unit both include a voltage following unit, a filtering unit, and a program-controlled amplification unit, an input terminal of the MCU is connected to an output terminal of the program-controlled amplification unit, and an output terminal of the MCU is separately connected to an input terminal of the filtering unit and an input terminal of the program-controlled amplification unit; and the MCU is configured to control filtering and denoising of the vibration conditioning unit and the ultrasonic conditioning unit, and adjust an amplification factor of adaptive amplification based on feedback signals output by the vibration conditioning unit and the ultrasonic conditioning unit. The flexible module is provided with the adaptive conditioning circuit supporting ultrasonic-vibration fusion. The present disclosure can adaptively amplify and filter an ultrasonic-vibration fusion signal, and has advantages of adaptive amplification, adaptive filtering, high implantation reliability, strong anti-interference performance, and the like.
