• Patients

Top Ten Wants:

Concept Selection:

Key Metrics Target ValuesAccuracy +/- 2.5 degrees

Cost $200.00

Cycles to Failure 50,000

Resistance 35,000 ohms

Final Concept: Proof of Concept Prototype:

Project Transition:

Testing:• Attachment of sensors• Effect of backing thickness• Need for electrical connection stiffener• Behavior of sensors:

•Tension Test•Bend Radius Test•Pressure Test•Twist Test

• Replace Sensors with Peratech QTC Technology

• Rewire with Calmont brand wire

• Improve DAQ system (USB Port Input)

• Improve LabView Program

LabView DAQ Program:

Glove with Sensors:

Background:

During a hand therapy session, physical therapists must manually measure the angle of each joint in a patient’s hand and wrist.

Features:

• Spectra Symbol flex sensors glued to a nylon knit comfort glove.

• Sensors wired with 24 gauge wire to an eight- channel DAQ board.

• Data collected using LabView, which will convert voltage readings to angular measurements.

• Stiffeners made of polypropylene stabilize and protect the electrical connections on the sensors.

Problem Statement:

Glove with Model Sensors and Securing

Devices:

Circuit Diagram and Test Setup:

Subsystems:

Selected Concepts:

• Sensors – Peratech “QTC” material• Wiring – Calmont brand wire• Glove – Knit “Comfort glove”• DAQ – LabView

Used in Prototype:

• Sensors – Spectra Symbol flex sensors• Wiring – Copper wire

Results:•Optimal backing is the medium-thickness backing (three layers of packing tape).

• No effect from pressure.

• Minimal effects from tension and twist.

• Bend radius has no effect on voltage readings.

•An electrical connection stiffener is necessary for consistent results.
