Final Concept
Proof of Concept Prototype
Background
Glove with Model Sensors and Securing Devices
Circuit Diagram and Test Setup
LabView DAQ Program
During a hand therapy session, physical
therapists must manually measure the angle of
each joint in a patients hand and wrist.
Problem Statement
Our goal is to design, develop, produce, and test
a prototypic, low-cost, and functional glove that
will sense key finger, thumb, and wrist positions
using compliant advanced technologies.
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

• Patients

Results
Key Metrics Target Values
Accuracy /- 2.5 degrees
Cost 200.00
Cycles to Failure 50,000
Resistance 35,000 ohms

• 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.

Features
Subsystems

• 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.
