Active Technology raises 330 million yuan for a brain interface that records 1,024 channels of neural activity

On August 3, Shanghai-based Active Technology announced a 330 million yuan angel round. TechNode describes it as the largest angel investment in China’s brain-computer interface sector. The company plans to spend the funds on equipment, manufacturing facilities, recruitment, and preparations for a clinical trial of its Tianshu motor system.

An invasive brain-computer interface records electrical activity from neurons directly in the brain. Flexible electrodes are placed in the brain or on its surface. Microchips amplify and digitize the signals, and software associates their patterns with a person’s attempt to move. The system then sends a command to a cursor, speech synthesizer, or another device. Active Technology is developing Tianshu for people who have lost the ability to move or speak after a stroke, spinal cord injury, or ALS.

Tianshu operates across 1,024 channels, which means that the system receives signals from 1,024 recording lines simultaneously. The company reported that the system passed type testing in November 2025, confirming that the device met its technical requirements. The next stated milestone is a clinical trial.

Active Technology already has a 2,500 square meter facility with a GMP area, where manufacturing follows quality control requirements. By the end of 2026, the company plans to open a headquarters with more than 10,000 square meters of space for microfabrication and nanofabrication.

The round will fund every part of the system that must be ready before the trial: electrode production, signal recording electronics, signal decoding software, quality control, and clinical work. Advancing a brain-computer interface to a clinical trial requires all these components to work together.
