Majority is not suitable for measuring plantar pressure there are volume is too big or the reason such as poor accuracy.So biography that the system uses
Sensor needs the features such as comfortable and easy to wear, small, precision is high.According to these features, the more of plantar pressure measurement are considered
A factor, have finally chosen FSR402 force-sensing sensors as measuring cell.The operation principle of FSR402 force-sensing sensors such as Fig. 4
It is shown.When the pressure for coming from the external world acts on the induction zone of force-sensing sensor, the resistance value of FSR402 can change.And with
The increase of external forces, the resistance value of FSR402 can be reduced.FSR402 provides two output pins, passes through point of external circuits
Pressure value is converted to magnitude of voltage and measured by pressure principle.
FSR402 force-sensing sensors are made of high molecular polymer film, length 53mm, sensitive part it is a diameter of
7.6mm, thickness 0.3mm, have the characteristics that slim, soft, compact, the detection of suitable plantar pressure.With surface pressing
Increase, the resistance value of FSR reduces, and has preferable sensitivity.Pressure signal measuring circuit is electric by FSR caused by plantar pressure
The change of resistance is converted to voltage signal, is output to central control module data acquisition.Since FSR is piezoresistive type sensors,
And electrical conductivity and pressure value are linear relationships.
