Would you pay extra for an exoskeleton that makes swimming less tiring?
Researchers at the Shenzhen Institute of Advanced Technology have developed two underwater exoskeleton systems, PEAKED and KAED, designed to assist divers' movement. The work is research-stage, described in a study published in Science Robotics, and no commercial availability has been announced.
Why it matters
Underwater propulsion is physically demanding, and the systems aim to cut the effort divers spend swimming. The approach extends wearable robotics, which has largely been developed for land-based mobility, into a harsh aquatic environment where reliability, waterproofing and power are hard constraints.
In controlled tests, PEAKED cut respiratory minute volume by up to 29.77% during flutter-kicking and improved a 50m underwater sprint by 8.1%, both measured against unassisted swimming. The study does not report sample sizes or the broader range of conditions tested, and the systems' longer-term reliability under real dive conditions remains untested.
The players
Shenzhen Institute of Advanced Technology
A Chinese research institute in Shenzhen whose robotics work includes the PEAKED and KAED underwater exoskeleton systems.
The details
PEAKED uses a flexible robotic structure worn around the hips and legs, while KAED is a rigid exoskeleton built to assist kicking motions. Both systems carry waterproof motors, batteries, sensors and control electronics, and they predict shifts in kicking frequency so that their assistance stays synchronised with the diver's natural movement. Respiratory minute volume, the amount of air a person breathes per minute, serves as a proxy for effort: lower values indicate the body is working less hard to sustain the same movement.

The Tech Race
Wearable exoskeletons have been developed mainly for land-based walking and lifting, so applying the approach underwater is a comparatively unexplored direction. The Shenzhen work positions China's research institutions in this niche, though the field-level competitive landscape for underwater wearable robotics is not detailed in the study.
The systems are not yet commercially available, and no price or release date has been announced. Divers may eventually access them through specialist dive centres and liveaboard operators offering rental options, though the systems are expected to be expensive at least initially.
The takeaway
Watch for independent replication of the test figures and for any pricing or pilot-rental announcement from the research team or dive operators. Early adoption is most likely to come through rental models rather than direct consumer purchase.
