How a Matrix Sensor is Made

Pressure mapping sensors are ultra-thin pressure-sensitive resistors (aka, tactile array sensors) that are used capture pressure data between nearly any two surfaces. Each sensor consists of intersecting rows and columns of conductive material. At each intersection is a layer of pressure-sensitive material. As pressure is applied to the sensing area, the resistance of the pressure-sensitive material changes. Scanning electronics connected to the sensor collects and converts this resistance change into digital signal, which is then transmitted to a computer for real-time analysis



Tekscan Sensor Properties & Performance

Figure 1: Typical Sensor PerformanceFigure 1: Typical Sensor PerformanceMatrix sensors (arrays) are available in a wide variety of shapes and sizes. They are also available in various pressure ranges from 0-14 kPa to 0-207 MPa. Custom designed shapes, sizes, and sensitivities are also available. Typical system performance is shown in Figure 1.

  • Resistance of the sensing elements (Sensels™) varies inversely with applied load.
  • The system linearizes sensor output into digital counts, or “raw” values on a scale from 0-255.
  • Calibration converts raw values into engineering units, such as psi or kPa.

Data Acquisition Electronics

Figure 2: Electronics SchematicFigure 2: Electronics SchematicTekscan’s interface products employ sophisticated microprocessor based circuitry to control scanning sequence and frequency, adjust sensitivity, and optimize the performance of matrix-based sensors.

Figure 2 demonstrates the sensing system and a simplified electrical schematic of the 8-bit electronics (255 levels) that scan the intersecting points of the sensor’s rows and columns and measure the resistance at each crossing point or sensing element (Sensel). The Sensels are read in the presence of multiple contacts while simultaneously limiting the possible current flow through the device. Each Sensel is represented by a variable resistor whose value is highest when no force is applied to it.

Tekscan systems have different options for electronics depending on the application requirements.

Sports AT Software for Balance Error AssessmentSports AT Software for Balance Error AssessmentHigh-Speed Systems

Tekscan’s high-speed systems are simplified matrices or single load cell configurations. The current maximum sampling rate for an integrated system is 20 kHz in a 44 load cell configuration. This high sampling rate is possible due to the extreme thinness and the relatively high spring constant of our sensor materials (a rise time of less than 20 microseconds). The ability to directly instrument the impact surface greatly enhances overall test accuracy. No other system solution is as adaptable and affordable.

I-Scan Pressure Mapping SoftwareI-Scan Pressure Mapping SoftwareMaking this possible is Tekscan’s custom data acquisition electronics and software. The data acquisition software consists of low level sampling control, sensitivity adjustment, and signal processing. This software optimizes the performance of the system in the acquisition of force or pressure data from our matrix-based and FlexiForce sensors.

With its Windows®-compatible software, the Tekscan system is simple to operate. Whether you choose a standard or a custom package, your system will respond quickly to your most important and frequent needs with graphically informative displays and intuitive operations.
