The quality in-shoe dynamic pressure measuring system


insole testing with the new pedar system

The pedar system is an accurate and reliable pressure distribution measuring system for monitoring local loads between the foot and the shoe. The pedar-x offers the ultimate versatility with its multiple standard features and operating modes. The pedar-x can be tethered to a PC via a fiber optic USB cable. It can function in a mobile capacity with its built-in state of the art BluetoothTM technology that is able to communicate with BluetoothTM compatible pocket, notebook, or standard PC's. And, as yet another alternative, the pedar-x has a built-in flash memory storage allowing data to be collected anywhere and later downloaded to the computer.

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 whole plantar
surface of the foot or sensor pads for the dorsal, medial or lateral areas of the foot. The pedar system allows multiple synchronisation options to use with EMG and video systems for gait analysis.

BluetoothTM telemetry
The pedar functions with Bluetooth TM wireless telemetry systems in a wide range. The pedar system comes with a built-in Bluetooth TM system and communicates with various Bluetooth TM PC adapters. 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-pda
The pedar-pda software communicates with a Windows based handheld personal digital assistant (called PDA or Pocket PC). pedar-pda data collection and presentation is performed with the handheld. Additional functions such as sensor calibration and data analysis are completed on a PC. The PDA transfers the data to a notebook or desktop computer, using the MS ActiveSync® software.

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.

pedar software
The pedar data acquisition software contains many helpful and user friendly options for fast pressure data collection and presentation.
