Cocoon
Cocoon is an advanced safety platform designed to protect the most vulnerable road users: children in bike seats. While traditional helmets offer basic protection, Cocoon Airbag Protection introduces a sophisticated AI-powered airbag and sensor system that provides a "safety envelope" during high-impact collisions.
This project involves a strategic collaboration with Tlera Corporation to integrate specialized expertise in embedded electronics and access to a Silicon Valley network.
This partnership is designed to bridge the critical gap between initial design and global production. The current project phase will culminate in the development of a full-scale prototype, establishing a new standard for family cycling safety.
Cyclists, especially children in bike seats, face major safety risks in traffic. Current protective equipment, such as helmets, provide limited protection in high-impact collisions. Research shows that in crashes, bike-mounted child seats can exceed safe head injury limits by 23 times.
Cocoon Airbag Protection develops the world’s safest child bike seat with a AI-powered patented airbag—for full-body crash protection. Cocoon provides, in addition to the helmet, an enhanced safety layer that can minimize potential injuries and save lives. Tests show Cocoon reduces head injury risk by up to 315 times.
The project leverages Sweden’s strong mobility ecosystem and builds on collaboration with Tlera Corporation with expertise in embedded electronics, design, and sensor applications, and a Silicon Valley network for prototyping, scaling, and production.
The project
The project aims to develop an electronics design advancing Cocoon’s airbag and sensor platform into a production-ready, designed-for-manufacture prototype. It will integrate accelerometers, signal processing, and Bluetooth communication into a modular, repairable system.
A full-scale prototype with production-ready PCB and firmware will be demonstrated during the project.
Project Goals
• Advance Cocoon’s sensor platform to a production-ready prototype
• Develop accelerometer and Bluetooth drivers for a connected solution.
• Create a modular, self-diagnostic design supporting Cocoon’s circular subscription model.
• Develop ML algorithms to improve detection speed, reduce complexity, lower power use, and extend battery life—enhancing
Cocoon’s prototype and giving Tlera the opportunity to apply its advanced ML sensor expertise to other projects. This automated decision-making advances broader safety systems for urban mobility.
• Leverage Tlera Corp’s Silicon Valley network and U.S. productization expertise to
accelerate market readiness and future international growth.
