Conformable TactArray
Accurately measure and map pressures around curved surfaces
The Conformable TactArray is a ~1mm thick flexible sensor constructed from soft, conductive cloth and captures pressure distribution between two objects in direct physical contact. The Conformable TactArray can accommodate varying degrees of curvature and can output accurate, repeatable data even while wrapped around irregular shapes.
Key Features and Benefits:
Maintain high-resolution and capture quality data even around complex shapes
High resolution, sensitivity, and repeatability allow for consistent capture of accurate data
The sensors can capture a minimum sensing pressure of 10 Pascal
Save time and improve results through repeatable accuracy and less recalibration time needed
Available in a wide range of size configurations, pressure ranges, and resolutions
Comes standard with the powerful Chameleon Visualization Software
Description
TactArray Systems capture pressure distribution between two objects in direct physical contact. By placing TactArray sensors between objects, wrapping them around shapes, or applying them to a flat surface, product developers and researchers can measure and visualize pressure information in their applications.
PPS’s Conformable TactArray (CTA) Systems are the only soft and flexible pressure sensor on the market offering high sensor performance on multi-curved surfaces. The system comprises a sensor, the electronics and visualization software. The conformable sensor is constructed from soft and flexible conductive cloth that captures pressure changes as low as 10 Pa with high accuracy, even when wrapped around complex geometries. Available in a wide range of size configurations, pressure ranges, and resolutions for your custom application.
Conformability
Constructed from soft, conductive cloth, the Conformable TactArray (CTA) is a flexible capacitive sensor array that can accommodate varying degrees of curvature. As a standalone sensor it can accommodate simple curvatures. We can also custom build it to be mounted on compound curvatures. Standalone, the cloth-like surface of the CTA is suitable for human skin contact and often integrated into a stretchable cloth band or a mask.
Key Features:
Active Areas ranging from 64 x 64 mm to 320 x 320 mm.
Sensing element resolution: 2 x 2 mm to 10 x 10 mm
Can be built with full scale pressure ranges between 2 psi and 80 psi
Can be used in environments with temperatures between –20°C and 85°C
Capturing pressures as low as 0.0015 psi (10 Pascal, 0.001 N/cm^2)
Thin construction (<1.0 mm thick)
Example Applications:
As a standalone sensor, the CTA can accommodate simple curvatures. In this format, the cloth-like surface of the CTA is suitable for human skin contact and often integrated into a stretchable cloth band or a mask. For compound or complex substrates, the sensor can be custom-built (molded onto) the complex surface without compromising data quality.
