In a groundbreaking leap for neuroscience and microtechnology, Chinese researchers have unveiled the world’s lightest brain chip — weighing just 74 milligrams. Remarkably compact and efficient, the chip is so small it can be implanted in and control the flight of a live bee.
The innovation, developed by a team of scientists at Zhejiang University, marks a major advancement in brain-computer interface (BCI) technology. Designed to interface directly with the nervous system of small animals, the chip can wirelessly transmit and receive signals, allowing researchers to influence the insect’s behavior in real time.

Demonstrations revealed that the chip could guide the direction of a bee’s flight by stimulating specific neural pathways, essentially turning the insect into a controllable bio-robot. The implications are vast — from enhanced pollination research and environmental monitoring to potential future applications in search-and-rescue operations using insect drones.
This achievement positions China at the forefront of ultra-light BCI development, with potential implications beyond insect control. Experts suggest similar technology could one day be adapted for use in medical treatments, micro-robotics, or even the enhancement of human-machine symbiosis.
