Comparisons among current test methods.

Sensor type	Weight (g)	Core idea	Influence of layout technique	Influence of temperature	Experiment type
Strain pressure sensor [8]	5.67	Stress change on the fabric surface	Great but not handled	Temperature influence considered and half-bridge temperature compensated	Low-speed wind tunnel experiment and drop experiment
-type sensor [10]	2.7	Good structure for stress transmitting	Relatively great but not handled	Temperature influence considered and strain gauge compensated	Drop experiment and low-speed wind tunnel experiment
CPC composite material sensor [1, 11]	≤1.2; The storage device is deployed on the surface of the parachute; Weight: 10 g	Stress change on the fabric surface	Limited and compensated on the coating thickness	Not compensated; subzero temperature not analyzed	Drop experiment
Fiber sensor [12, 13]	Uncertain	Stress change tested by fiber deformation level	Limited and not handled	Temperature influence considered and strain gauge compensated	Drop experiment
Improved type sensor module (IOS)	2.2	Compensation on the influencing during the test	There is influence but it is compensated	Temperature influence considered and full-bridge temperature compensated	Drop experiment and low-speed wind tunnel experiment
