中文摘要:
本文为治疗人体软组织损伤，减轻疼痛，加快病情的好转，而设计一款可穿戴式低强度聚焦超声治疗装置.该设备采用QI标准无线充电模块为整个装置提供能源，经高转换率的集成升压电路将3.3 V转为5 V，为驱动电路提供电压，再由采用nrf24l01模块传输的遥控器控制超声发生康复贴，即STM32L151单片机结合PID算法产生1 MHz PWM波，控制驱动电路驱动压电陶瓷片产生频率为1 MHz，强度为100 mW/cm2、132 mW/cm2、150 mW/cm2三档位超声波.该装置具有体积小，充电快，重量轻，成本低，无需耦合剂，可穿戴，电-声转换效率高的特点.
English Summary:
In this paper, a wearable low-intensity focused ultrasound therapy device was designed to treat human soft tissue injury, relieve pain, and speed up the condition. Firstly, a QI standard wireless charging module was used to provide energy for the entire device. And an integrated conversion circuit with high conversion rate was designed to convert the voltage from 3.3 V to 5 V, providing voltage for the driving circuit. Then the remote control device controlled by the nRF24L01 module was used to control the ultrasonic rehabilitation paste. The STM32L151 microcontroller combined with PID algorithm can produce 1 MHz PWM wave, and the control drive circuit can drive piezoelectric ceramic chip to produce frequency of 1 MHz, strength of 100 mW/cm2, 132 mW/cm2, 150 mW/cm2 three gears ultrasonic. The device possesses the characteristics, including small size, fast charging, light weight, low cost, no coupling agent, wearable, high electro-acoustic conversion efficiency.
