Landsdowne Labs, a spinout from the Karp Lab at Brigham and Women’s Hospital and the Langer Lab at MIT, is rapidly advancing its first product, ChildLok– a technology designed to deactivate batteries following accidental ingestion, made possible by advanced material science. The Childlok technology has passed rigorous testing to date and is being readied for large scale manufacturing. The timing is critical!  Just this week, an article published in the journal Pediatrics (an official journal of the American Academy of Pediatrics) stated that accidental poisonings of children by button batteries is on the rise. There is, on average, a visit to an ER every 1.25 hours among children under 18.  Just a few weeks ago, President Biden signed “Reese’s Law” into effect to solve this crisis with improved packaging and device securement for button battery housings  To maximally reduce injuries, Landsdowne Labs is advancing a new rapidly scaleable turnkey battery design.  Additionally, the company recently won a Phase 1 NSF SBIR/STTR grant to accelerate the translation of the ChildLok technology to help prevent child injuries from ingested button and coin cell batteries.
