Description
E2517 flexible film pressure sensor is a flexible pressure sensor product specially designed and developed by Suzhou Nengstar Electronics for TWS earphone. It can bring real pressure sensing function to TWS earphone.
The E2517 has high sensitivity and resolution, maintains linear output over a wide range, and can detect finger pressed micron deformation. In addition, E2517 can also be expanded to detect force value grading, force value change detection, multi-point detection, etc.
E2517 also has good flexibility and can be used for pressure detection of plane or curved structure, easily adapt to more complex structural conditions.
Advantage
Designed and developed for TWS earphone pressure sensing scheme; High sensitivity, can respond to pressure below 10GF; Flexible, bending resistance; Based on flexible nanomaterials, the response speed is fast; Long life, can withstand more than 1 million times of repeated press; Low power consumption (typical value: 0uA in standby mode) Sensor profile can be customized Sensor range parameters can be customized
Application
True Wireless Stereo Earphone Sensor
