Hand Sensor Array (HSA)

The HSA comes in either an 8 x 8 array of 1" sensors or as a 24 x 24 array of 5/16" sensors inside a flexible mat material. The HSA can be used for numerous applications where you grasp, grab or apply a force to a tool, device or object. You can easily see the pattern of force being exerted (via the software's color mapping display) of each finger as an object is grasped.

Similar, to our other mapping products (e.g. seat or back) the system will provide a detailed recording of each sensors PSIU readings over time as well as a real-time display showing each sensors pressure (unless the system is being used in data logging mode). The maximum force that can be measured is 30 psi.

The HSA uses SoftFlex, a new generation of FSA sensing mats that are more durable, flexible and drapable. They feel soft like three layers of fabric and conform easily to soft interface shapes.

The HSA can be added to an existing system or configured with FSA 4D software, Universal System Base, High Pressure Calibration Kit, Manual and Trigger. A telemetry option is available.

Users can also use the OCX control in LabView to set audible alarms when specified PSI levels are exceeded.

Data gathered can easily be transferred to a spreadsheet to facilitate in depth statistical analysis.

FSA 4D software allows for video synchronization of the captured data with individual video frames for users of Windows XP.
