Bioinspired cellular actuators

Introduction

BiCeps aims to revolutionize mechanical motion generation by designing, developing, and fabricating muscle-inspired actuators. These innovative microscale devices will be based on active cellular metamaterials capable of contracting in response to stimuli, emulating the functional mechanisms of a remarkable biological actuator.

Objectives

This objective will be realized through the continuous integration of stiff structural materials with active stimuli-responsive counterparts. Multi-material additive manufacturing and allied technologies will allow the fabrication of artificial sarcomeres, incorporating into 2D and 3D actuator arrays, and enabling macroscopic-scale contraction generating force through collective unit cell deformation.

Advantages

This groundbreaking approach overcomes the limitations associated with current active polymeric materials in soft robots, particularly their lack of structural stability. BiCeps aims to produce robust, enduring, and reliable actuators suitable for various technical applications, potentially replacing conventional electric motors and combustion engines in diverse sectors such as:

• Industrial
• Residential
• Transportation

Challenges

A critical priority for BiCeps is addressing the challenges associated with fabricating micro-architected cellular materials using high-strength materials. The risks involve uncovering optimal additive manufacturing and post-processing conditions and elucidating the principles of the actuator.

Expertise

The consortium's expertise in multi-material additive manufacturing will play a crucial role in ensuring the precision and performance of muscle-inspired actuators.

Market Opportunities

The potential market opportunities for these new actuators are immense. Even capturing a modest 1% of the global motor market could represent a significant investment opportunity, given the projected growth and value of the sector.
