语音交互与力感知式智能牙周探针开发

Aimed at overcoming the shortcomings of the current periodontal probes in probing force controlling and probing parameters auto-recording, this paper designs and verifies a portable, wireless and smart periodontal probe featuring speech interaction and force sensing. Its probing forcing sensing module is constructed. Its software and hardware are developed. Periodontal probing experiments are conducted. The calculated values of the probing forcing sensing module shows a maximum error of 2.49% compared to the mean tested data. The correct rate of speech recognition for some giving phrases is higher than 98%. In periodontal probing experiments, the probe interacts fluently with testers, performing correct display of probing force range and accurate bluetooth communication, being a new type of periodontal probe with advanced performance, convenient usage and friendly experience.
