High precision 3D plantar pressure detection

Shilian Boyan (Beijing) Technology Co., Ltd. specializes in providing stress analysis and other services. For more information, please contact Manager Ma

Core advantage: Empowered by technology, redefining gait analysis

• High sensitivity perception, precise data

• Using high-sensitivity piezoresistive composite film material, with built-in carbon nano sensor coating, 10 pressure sensors are distributed per square centimeter, and a 3D pressure grid is constructed with 50000+sensing units. The dynamic sensing range is wide, the load capacity is strong, and the linearity and repeatability accurately capture every pressure change during walking, running, and other movements in barefoot/shoe state.

• Intelligent processing, efficient analysis

• The high-performance MCU acquisition and processing circuit is equipped with a 12 bit ADC and PGA, with an ultra-high acquisition frame rate of 150Hz. Combined with adaptive algorithms, it outputs real-time raw data of plantar pressure, 2D/3D pressure images, and gait trajectories, and synchronously generates professional evaluation reports, providing quantitative basis for clinical decision-making.

• Craftsmanship design, quality assurance

• Ergonomic structure: High quality aluminum alloy shell, total weight<15Kg, aviation USB self-locking interface to prevent detachment, easy and stable operation.

• Visual interaction: The high-definition LED display light board supports custom color modes and logo display, presenting pressure changes intuitively.

• Wide range adaptation: stable operation under working temperature of -20 ℃~60 ℃ and humidity of ≤ 85% RH, compatible with Win7/10 and above systems, suitable for multi-core processors and 8G+memory devices.

Functional Matrix: Comprehensive Analysis, Guarding Foot Health

Core functions of the detection dimension include static foot posture analysis, foot length/width measurement, arch index evaluation, flat foot screening, monitoring of hallux valgus angle, analysis of pressure ratio between front and back/left and right feet, dynamic gait analysis of pressure distribution trajectory, pressure peak positioning, degree of foot inside/outside rotation, gait cycle parameters (standing/swinging period, etc.), walking speed/step length/step width measurement report and application support. Data storage and report sharing are provided, personalized orthopedic insole intervention suggestions are provided, and pre - and post-operative efficacy tracking is assisted

Professional application scenarios to assist precision medicine

• Prevention and control of diabetes foot: early identify abnormal plantar pressure, joint clinical examination and early warning of diabetes foot risk to reduce amputation rate.

• Orthopedics and Rehabilitation Medicine: Quantitatively evaluate the treatment effect of bone and joint diseases, the recovery of foot function before and after surgery, and develop precise rehabilitation plans.

• Body posture and exercise health: Screening for arch abnormalities (such as high arch feet and flat feet), intervening in issues such as long and short legs, pelvic tilt, and scoliosis caused by foot mechanics imbalance, and adapting to the gait optimization needs of the exercise population.

Data example: Speak with numbers, make health traceable

• Static report (case: TEST)

• Left foot high arch foot level 1 (arch index AI<0.21), right foot normal;

• The excessive weight-bearing capacity of the right foot indicates a risk of pressure imbalance on both sides of the body, and attention should be paid to the mechanical compensation of the lower limbs.

• Gait Report (Case: Zhangsan)

• Step length: left 39.31cm/right 40.02cm, step speed 2.13km/h, double support period accounts for 36.72%, reflecting walking stability;

• Foot deviation angle: 1.53 ° to the left/8.38 ° to the right. Attention should be paid to abnormal wear and tear in the right foot abduction trend.
