loadsol®: plantar normal force inside footwear

The loadsol® system* enables the measurement of the normal ground reaction force on the plantar surface of the foot in both standing and dynamic movements. Utilizing one flexible, flat sensor which covers the entire plantar surface of the foot, loadsol® measures the force between the foot and the shoe, regardless of which part of the foot is in contact with the insole. The loadsol® sensor is based on new patented technology and due to its linear properties also measures partial loads accurately.
The loadsol® is used for applications where the capture of the total force on the foot is needed. The loadsol® does not capture the local pressure distribution under the foot. For this application novel’s pedar system is the gold standard.

loadsol® technology has matchbox-sized electronics and communicates wirelessly via Bluetooth® with a smartphone. The force values are displayed on the smartphone in real time. The user can receive immediate biofeedback regarding the load on the foot via an auditory, visual, or vibratory signal. The measured data can be stored on the smartphone and to a cloud or a data server, and additionally transferred to a computer for a more detailed analysis. Long-term measurements allow the evaluation of various parameters.

The loadsol® app is easy to operate and if required allows for extensive display and evaluation of various parameters.

In order to further evaluate the acquired data for other applications, the data can be exported to an ASCII file. Additionally, the Windows loadpad® analysis software offers an extensive evaluation of the loadsol® data on the computer.

The loadsol® insole conforms well to surfaces and therefore it is possible to wear a shoe inlay in addition to the loadsol® measuring insoles. The electronics were intentionally not integrated into the thin loadsol® sensor to minimize a proprioception change of the plantar surface of the foot, the biomechanics of the gait, as well as the function of a corrective orthotic. The miniature electronics can be attached to the upper part of the shoe, i.e. the laces.

The loadsol® insole is available in shoe sizes 36 to 49 (European sizes) and in four versions with different sensor area layouts. Thus the load on the foot can also be captured separately in up to three subareas. For specific applications there are additional customizable divisions and sizes available.

The loadsol® sensor technology is also available as a dorsal pad for measurement on the dorsum of the foot. The dorsal pad can be used to examine the comfort of the shoe.
