[Retracted] Fabrication of Nanofiber Flexible Pressure Sensor and Application in Human Motion Monitoring

Table 1

Different strengths and weaknesses of PVDF film preparation methods.

	Advantage	Shortcoming
Elyncal spin coating	The process is simple and mature, and the film is thin	Laboratory research, difficult to batch production
Solution casting method	Easy to operate	The film is thicker; it is easy to produce defects
Vacuum thermal evaporation method	Film uniformity is better	Equipment requires a high requirements
Immersion portram	Thin film is thin; easy to induce orientation	Film thickness is difficult to control
Thermocompression method	Easy to film formation	High experimental cost
