Scientists in Switzerland are developing biocomputers made from living human cells, marking a major leap toward merging biology with technology.
At the FinalSpark lab, researchers are growing tiny brain-like structures, called organoids, from human skin cells. These clusters of neurons are connected to electrodes, allowing them to send and receive signals — essentially functioning as mini living computers.
Dr. Fred Jordan, co-founder of FinalSpark, said these “wetware” systems could one day power data centers, offering faster learning and far lower energy use than traditional computers.
The organoids are kept alive in lab dishes for up to four months, but scientists say maintaining them is difficult since they lack blood vessels. Despite the challenges, early tests show the neurons can respond to stimuli and may even demonstrate basic learning.
Similar projects are underway in Australia and the US, where researchers are using brain cells to play games and study neurological diseases. Experts believe biocomputing won’t replace silicon chips, but could complement them in AI and medical research.
Dr. Jordan said the work feels like science fiction coming to life: “We’re building computers that actually think — using living cells.”
