This piece began as an exploration of exhaustion, heartbreak, and the constant pressure to create. The pumping mechanism reflects the emotional and physical rhythms we carry. A reminder of fragility, resilience, and the body’s unrelenting drive to keep going.

Each bag is alive.
The Pumping Heart Bag™ is a sculptural tech piece that blurs the line between body and object. Designed and engineered by wearable-tech artist Brittany Anne Cohen, each bag is 3D-sculpted and hand-finished. No two will ever be alike — imperfections in the print, the way the liquid flows, even the rhythm of the pump create a singular experience every time you power it on.
Hold it close and you’ll hear the heartbeat. Feel the vibrations. Watch liquid pulse through transparent tubing in patterns that can never be replicated. It’s art you wear — a piece that feels uncannily alive.
Over two years of obsessive experimentation went into bringing this vision to life — finding the perfect pump, the right liquid, the correct tubing, and a system that creates the illusion of blood flowing in real time.
This is a limited release. Once a drop sells out, availability closes until the next release. Each piece is final sale

One of a Kind: Every bag is unique. No two will ever produce the exact same liquid flow effect.
Handcrafted + 3D Printed: Each bag is 3D printed and finished by hand. Small surface variations or blemishes are natural to the process and part of its individuality.
Fluid Flow Behavior: As the bag runs, the liquids may naturally blend and appear less defined — this is normal and part of the living nature of the piece. When this happens, the liquids can always be returned to a more distinct look. If you’d like to reset the flow, follow the steps below.
Resetting the Flow: If you'd like to restore the liquids to a mored distinct pattern:
• Turn the bag off and allow it to settle.
• Keep it resting vertically.
• Once restarted, the liquids will gradually reform into a more defined, separated pattern/
