Grip System

Quantify forces applied by the human hand while grasping objects.

Tactile Grip Force and Pressure Sensing

The Grip™ system measures and evaluates static and dynamic pressures from grasping objects. Grip measures interface pressure for human hand and finger gripping applications to assess comfort, design, and ergonomics. The system is used to improve design for a more ergonomically sound product, study carpal tunnel and repetitive motion syndrome, or analyze the human hold on various tools and sports equipment. It is an ideal tool for collecting vital information and insight to enhance product design, manufacturing, quality, and research.
Key Features
  •  Simultaneous measurement of left and right hands
  • Numerous independent sensing elements for localized detection and sensing of pressure points
  • One subject can grip several objects in many ways, once the hand is instrumented
  • High scanning rates of up to 750Hz (tethered version)
  • Paper-thin sensor form factor allows for full range of hand motion
  • One size fits all
  • Durable and reusable sensor

Grip System Configurations

The Grip system is available tethered or untethered for increased mobility and range of measurement. Your specific application will determine the best-suited connection type.
Tethered Model
Every VersaTek™ based system uses specially designed scanning electronics called Cuffs. The Cuffs connect to the sensor to gather data, which is then processed and sent to your computer, via USB connection. VersaTek electronics run at the fastest speeds and are compatible with other VersaTek sensors, giving you the ability to add in-shoe, prosthetic, grip, and seating & positioning capabilities to your Tekscan System.

Grip Sensor – 4256E

The Grip™ System uses a thin, high-resolution sensor that can be used directly on a hand or built into a glove. Each sensor has eighteen sensing regions that can be individually positioned over important anatomic sections of the fingers and palm. Gaps between the sensing areas allow the joints to be avoided, move freely, and not interfere with grip measurement. Each sensing region has multiple sensing elements (Sensels™) for localized identification of pressure points on the hand.
