pedar^®: Dynamic pressure distribution inside the footwear.

The pedar system is an accurate and reliable pressure distribution measuring system for monitoring local loads between the foot and the shoe. The pedar offers the ultimate versatility with its multiple standard features and operating modes. The pedar utilizes the plidar electronics. The plidar transmits the pressure data via WiFi to the computer, where it is displayed real time. It can also store data on-board with 32 GB memory.

54g of pure efficiency

The system is a tiny, lightweight and easy to use system with:

only 54g matchbox size electronics
scans 99 sensors at 400 Hz
set up time < 1 min, including mounting the sensors on subject

All of these features make the pedar system extremely mobile and flexible to meet virtually all testing needs such as walking, running, climbing stairs, carrying loads, playing soccer, or even riding a bicycle. The results are therefore more relevant to real-life.

The pedar system connects to highly conforming, elastic sensor insoles that cover the entire plantar surface of the foot, or to sensor pads for the dorsal, medial or lateral areas of the foot.

The pedar sensors use capacitive technology – known to provide the best accuracy for pressure measurement on the human body. The pedarsystem allows multiple synchronisation options to be used i.e. with video systems for gait analysis.

Applications of pedar system:

footwear shoe research and design
kinetic analysis of free gait in biomechanics
long term load monitoring
sport biomechanics
biofeedback

PEDAR - the most accurate foot pressure measurement insole

trublu calibration device
With the aid of the trublu calibration device, all sensors of the pedar system are individually calibrated. Calibration guarantees accurate and reproducible data and can be checked by the user at any time.

Wifi telemetry

The pedar works with Wifi telemetry system in a wide range. The pedar includes a built-in Wifi system and communicates with various Wifi routers connected to the PC. The telemetry allows the user to watch the subject and at the same time fully control the testing from a PC. The dynamic pressure data can be viewed online and the subject advised how to perform. The system is a perfect tool for teaching and for biofeedback testing.

pedar pad

The pedar pad is a highly flexible sensor for measurements on the dorsal side of the foot inside the shoe. It can be combined with pedar insoles for simultaneous measurement of the plantar and the dorsal aspect of the foot to monitor the shoe-fit.

Technical data for the pedar pad:
• Number of sensors: 56 (7 x 8)
• Size of one sensor: 10 x 20 mm²
• Sensor area: 70 x 160 mm²
• Pressure range: 15.0 – 600.0 kPa
• Sensor resolution: 0.5 sensor/cm²
