PPS’s TactArray instrumentation solutions include a flexible pressure sensing pad that captures pressure distribution between two objects in direct physical contact. TactArray solutions have given the “sense of touch” to many products or tools for their development, enabling PPS customers around the world to create many successful products.

Designed for engineers, researchers, and product designers that have a need to capture contact pressure distribution in their applications, PPS’s patented TactArray sensor technology enables a two-dimensional array of pressure sensing elements in a thin, continuous sheet.  By placing TactArray sensors between objects, wrapping them around shapes, or applying them to a flat surface, customers measure and visualize pressure information in their applications. Using this simple but powerful capacitive sensing approach, the TactArray systems provide a platform for the most repeatable and sensitive tactile sensors in the market today along with a wide variety of options for design.

All TactArray instrumentation solutions consist of TactArray sensors accommodating up to 8,192 sensing elements together. Using the included T4500 electronics with USB 2.0 interface to attach to a computer, TactArray solutions run PPS’s Chameleon image capture and analysis software. This industry-leading software is fully featured which means it can export replay, save test data, and perform analysis functions. Chameleon can also record and playback video with your data results for even greater insight and analysis.

The TactArray Instrumentation Solutions….

Provide high-resolution highly sensitive and repeatable array sensors that allow designers to develop the best product designs based on highly reliable, high-resolution data.

Deliver high performance capacitive sensing technology saves time and improves results by significantly reducing recalibration and repeated tests allowing developers to resolve problems and answer questions faster. Twice the repeatability, 100x better minimum pressure detection, and 50% better pressure sensing resolution compared to typical resistive tactile sensor technologies.

Feature Chameleon Visualization Software provides intuitive, easy to use, high-quality visualization and easy access to data for analysis and export to other applications. The software is fully featured which means export, replay, save and analysis functions are included with every system, unlike competitors who require a paid upgrade for these features.

Include the T4500 High speed USB 2.0 interface electronics that provides latency-free results in a plug and play environment.

TactArray Sensor Types

TactArray sensors are available in 4 material options: conformable from conductive cloth, stretchable engineered Spandex, industrial made of Polyimide, and hybrid combining conductive cloth and Polyimide.

The following table summarizes the primary differences of the different TactArray sensors:





Sensor Material Conductive Cloth Spandex Polyimide Cloth & Polyimide
Thickness 1mm 3mm 0.3mm 0.5mm
Max. Pressure Range 100 psi 50 psi 700 psi 100 psi
Temperature Range -20°C to 100°C -20°C to 50°C -40°C to 200°C -20°C to 100°C

PPS TactArray for Measuring Distributed Pressures

Conformable TactArray Sensor (CTS)

Constructed from soft and flexible conductive cloth that this pressure sensor pad measures approximately 1mm thick. Our CTS sensors….

  • Deliver high sensor performance in a flexible sensing pad that is moldable to multi-curved surfaces

  • Can wrap around simple geometries or be molded to more complex shapes without compromising data quality

  • Functions with maximum pressures from 1 - 100 psi within temperature ranges of –20° to 100°C

  • Are the most sensitive tactile sensors in the market, resolving to pressures as low as 10 Pascal

Stretchable TactArray Sensor (STS)

These flexible pressure sensor pads are engineered from extremely soft and conductive silver-metalized Spandex. Our STS sensors ….

  • Can stretch to 10% with negligible baseline shift and accommodate bending and flexing of surfaces

  • Are ideal for applications in which they are embedded into objects that are going to be deformed slightly through use, such as a seat cushion, mattress, or tight clothing

  • Are about 3mm thick and have more-limited layout options than CTS

  • Functions with maximum pressures from 5 psi to 50 psi within temperature ranges of –20° to 50°C

Industrial TactArray Sensor (ITS)

Optimized for applications involving extremely high temperatures and pressures, ITS sensors….

  • Feature flat and rigid Kapton construction about 0.3 mm in thickness

  • Can measure pressure distribution up to 700 psi in temperatures up to 200°C

  • Are not as flexible as CTS or STS but can accommodate moderate bending, making them fairly robust

Hybrid TactArray Sensors (HTS)

Combining the best of both material worlds, the HTS sensors….

  • Were developed for use in low-to-moderate pressure ranges

  • Are best suited for use in designs that require the sensor to be integrated into a product

  • Leverage the benefits of both conductive cloth and Polyimide
