Key Findings

  • 01Over 50% of reviewed wrist exoskeleton devices are designed as 'soft' exoskeletons.
  • 02Soft designs are favored for better kinematic compliance, ergonomics, and safety.
02

Application

Design takeaway

When designing wearable assistive devices, prioritize soft, compliant structures to enhance user comfort and natural movement, leading to greater acceptance and effectiveness.

How to apply

When designing any wearable technology, consider the use of flexible materials and adaptable structures that conform to the user's body and movements.

Project actions

  • 01When designing a wearable device, think about how it will feel on the skin and how it will move with the body.
  • 02Consider using flexible materials like silicone or fabric-based actuators instead of rigid plastics or metals where possible.
03

Method & Evidence

AimTo investigate the design trends in wearable wrist exoskeletons, focusing on the prevalence of soft designs and their impact on user factors.
MethodLiterature Review
ProcedureThe study reviewed existing literature and cataloged wearable wrist exoskeleton devices, categorizing them by design type (soft vs. rigid), actuation, sensing, and control strategies, with a focus on their intended application (rehabilitation, assistance, occupational).
Sample24 devices
ContextWearable assistive technology, specifically wrist exoskeletons for rehabilitation, assistance, and occupational use.

Variables

IVDesign type (soft vs. rigid exoskeleton)
DVUser comfort, perceived ease of movement, user acceptance
CVTask performed, duration of use, user's pre-existing condition

Strengths & Limitations

Strengths

  • +Provides a clear trend in current exoskeleton design.
  • +Highlights the importance of user comfort in technology development.

Limitations

The effectiveness of 'soft' designs might vary depending on the specific task and the required level of support. Not all applications can benefit from extreme flexibility.

Reliability & validity

The review's reliability depends on the comprehensiveness of the literature search. Validity is supported by the consistent findings across multiple devices. However, subjective interpretations of 'soft' could affect validity.

Think critically

To what extent does the 'softness' of an exoskeleton compromise its ability to provide significant mechanical support or force augmentation?

05

Design Principles

"User comfort and kinematic compliance are paramount for the successful integration of wearable assistive devices."

This insight is crucial for understanding how design choices directly impact user acceptance and effectiveness. For design, it highlights the importance of considering human physical and psychological factors when developing assistive technologies, moving beyond pure functionality to user-centric comfort and integration.

06

What This Means for Your Design

Making wrist braces (exoskeletons) soft makes them more comfortable and easier for people to wear and use.

How to use in your project

  • 1.Use this insight to justify the choice of materials and construction methods for a wearable prototype, explaining how softness enhances usability.
  • 2.In user testing, specifically ask participants about the comfort and 'naturalness' of the device's movement.
