Mind control device for bees developed by China weighs only 74 mg, offering 90% precision in movement—marking a major leap in surveillance and defence innovation. Ideal topic for UPSC, SSC, defence and science-related government exams.
Chinese Scientists Create World’s Lightest Mind‑Control Device for Bees
1. Overview of the Breakthrough
In a groundbreaking feat, researchers at Beijing Institute of Technology, under Professor Zhao Jieliang, have developed the world’s lightest brain-control device, weighing a mere 74 mg. This ultra-light implant attaches to a bee’s back and uses three fine needles to stimulate the brain via electrical pulses, directing flight movements—such as turning left or right, moving forward, or reversing—with a remarkable success rate of 90%.
2. Leveraging Bee Physiology
Worker bees naturally carry nectar loads up to 80% of their body weight and fly distances of about 5 km without rest. The researchers leveraged this inherent strength and efficiency, creating “insect-based robots” that combine biological mobility with artificial control for various mission types.
3. Technological Innovation
This device is notable for its lightweight and flexibility—its circuits are printed on polymer film as thin as insect wings. Previous versions, including those from Singapore, weighed over three times as much and were limited to beetles and cockroaches. The new design includes infrared remote-control chips enabling complex directional commands.
4. Testing and Performance
In lab tests, bees equipped with this device responded correctly about nine times out of ten. The technology was also trialled on cockroaches, guiding them along defined paths. However, insects exhibited fatigue after repeated stimulation, and their body parts sometimes reacted inconsistently.
5. Challenges and Next Steps
Key limitations remain—chiefly power supply and behavioral precision. The current device requires a wired power source; wireless batteries weigh around 600 mg, which bees cannot carry. Future work will focus on optimizing stimulation signals, power miniaturization, and expanding environmental sensors for enhanced applications.
6. Potential Applications
Research suggests these cyborg bees could perform covert reconnaissance, aid disaster relief, and assist in counterterrorism and narcotics operations. Their natural camouflage, long endurance, and flight agility may outperform mechanical drones in stealth and versatility.
