The objective of the experiments is to register the weight detected by the FSR sensors when all sensors are added independently, and also to detect and characterize the lifting and lowering activities.

Experiment I steps:

1) Sensors are initialized (the person’s weight (83kg) is registered as base weight).
2) Repeat 3 times:
a) Walk few steps.
b) Lift up 18.6kg weight from the ground.
c) Lower 18.6kg weight from the ground.

Experiment I. Weight detection.

Experiment I. Lifting and lowering detection.

Experiment II steps:

1) Sensors are initialized (the person’s weight (83kg) is registered as base weight).
2) Walk few steps.
3) Repeat 3 times:
a) Lift up 9.3kg weight from the ground.
b) Lower 9.3kg weight from the ground.

Experiment II. Weight detection.

Experiment II. Lifting and lowering detection.

The results show that the proposed insole FSR system is able to detect the weight of a person and the lifted weight, by integrating force sensors located under the shoes of a person. The FSR insole system integrate 8 force sensors per foot, divided in two modules, one module located under the heel area and the other under the foot metatarsals. In this configuration, the FSR insole system is able to measure the forces between 0 to 160kg.
