Pressure Measurement System

Measuring the foot plantar pressure has the potential to be an important tool in many areas such as enhancing sports performance, diagnosing diseases, and rehabilitation. In general, the plantar pressure sensor should have robustness, durability, and high repeatability, as it should measure the pressure due to body weight. Here, we present a novel insole foot plantar pressure sensor using a highly sensitive crack-based strain sensor. The sensor is made of elastomer, stainless steel, a crack-based sensor, and a 3D-printed frame. Insoles are made of elastomer with Shore A 40, which is used as part of the sensor, to distribute the load to the sensor. The 3D-printed frame and stainless steel prevent breakage of the crack-based sensor and enable elastic behavior. The sensor response is highly repeatable and shows excellent durability even after 20,000 cycles. We show that the insole pressure sensor can be used as a real-time monitoring system using the pressure visualization program.

Pressure Measurement System

According to the requirement of measurement of plantar pressure, this thesis puts forward a plan to construct a new insole plantar pressure system based on multifunction data acquisition modular and Test Point. Then the hardware part and software part are designed and developed respectively. The piezoelectric ceramic type sensors are designed, manufactured and calibrated according to scientific methods. Meanwhile, the DAQ card is selected carefully. Of course, the software part is developed based on Test Point. A series of tests are performed in order to validate the function of the plantar pressure measurement system. The results satisfy the anticipated design requirements. At last, the problems and application trend of the plantar pressure system are predicted.

Pressure Measurement System

Plantar pressure measurement is an essential and effective strategy in the assessment of foot musculoskeletal safety and footwear comfort. It is commonly applied in clinical gait analysis, sports and foot biomechanical studies. But most of the devices used for plantar pressure measurement are high cost and not readily available for the research. This study aims to present a low cost foot plantar pressure measurement system based on force sensitive resistor (FSR). The system is composed of low cost electronic instrumentation through FSR, arduino, LCD display, baseboard and a power bank. To verify the feasibility and effectiveness of the system, a linear load vs. pressure calibration test was made and a group of female participants performed static trials on heels of three different heights. Experimental results and comparative analysis showed that this system has stable performance in static measurements of plantar pressure.
