Grip™ System

grip analysis

Measure and record dynamic pressures and forces while grasping, gripping, holding, and using objects.

Grip Pressure and Force Measurement System Features:

Measures and records the dynamic pressures and forces your hands and fingers apply while grasping, gripping, holding, moving, lifting, and using objects
Displays and records the hand and finger pressures applied during these activities and gives insight into these movements and the product
Graphically displays and plots the forces and pressure distribution for different parts of the hand and fingers so you can analyze and quantitatively compare the grasping action and product designs from an ergonomic perspective
Measure the pressures required to grasp objects or analyze the pressure needed to open, close, or lift items

Benefits of Pressure Mapping:

Paper-thin sensor does not affect the grip “feel”
Flexibility of the sensor allows movement and conformability
Sensor fits right and left hand
Easily locate sensing pads to fit any size hand
Connections and wiring does not interfere with the gripping activity
Can detect peak pressure regions within a sensing pad
Sensors are durable and reusable

System Description

System Components

Grip Tethered

Wires connect the sensor and scanning electronics on the subject to the computer via USB port. Dynamic events are captured with scan rates of up to 750 Hz.

VersaTek Cuff(s)

(1) VersaTek 2-Port Hub

Grip Software CD

Sensor(s), Model# 4256E

Grip Wireless

Data is transmitted directly from the subject to the computer, allowing for a wide range of applications. The subject can be up to 100 meters away and data can be recorded and displayed on the computer in real time. A 100 Hz scan rate is available with wireless connectivity.

(2) VersaTek Cuffs

Every VersaTek based system uses specially designed scanning electronics called Cuffs. The Cuffs connect to the sensor, gather the data from the sensor, and then process and send this data to your computer via USB connection. VersaTek electronics sample 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.

Components depend on system configuration. Additional items may be included with your system purchase.
