Pressure Profile Systems (PPS) TactArray is a family of capacitive pressure-sensing arrays in the form of a thin, flexible sheet that can be wrapped around complex 3D shapes (e.g. humanoid gripper fingers, surgical tools). Each array element measures local pressure with high repeatability — the capacitive sensing principle provides 100× better minimum-pressure detection and 50% better pressure resolution than conventional resistive sensors.
Four main variants are available: Conformable TactArray (~1 mm thick, conforms to 3D shapes), Industrial TactArray (temperature range −40 °C to +200 °C, pressures up to 700 psi / ~48 bar), Hybrid TactArray (rigid base with flexible regions), and Stretchable TactArray (up to 10% stretch with preserved data quality). The maximum number of sensing elements per array is 8,192.
Each kit ships with the T4500 USB 2.0 interface electronics, Chameleon software for visualization and analysis (export, replay, video integration), and cabling. Data is synchronized with external video, enabling reconstruction of dynamic contact events.
TactArray is used by Microsoft, Google, Toyota, Honda, Canon, and Dyson — for humanoid gripper prototyping, surgical grip research (laparoscopy), in-vehicle pressure mapping, ergonomics of consumer products, and shoe-foot contact analysis. The manufacturer is PPS (Medical Tactile, Inc. / PPS UK Limited), with over 25 years of experience in tactile sensors.
