Mindtrix cortical visual reconstruction system
Mindtrix (明视脑机) is developing a visual cortex prosthesis for blind patients. The December 2025 human result came from a patient already undergoing epilepsy surgery, so the study hardware was temporary clinical electrodes, not the company’s own implant. Product details on the company site are listed separately and labeled.

Value and source scope
Device
Mindtrix (明视脑机) visual reconstruction system: smart glasses with camera, a handheld video processing unit (VPU), a wireless implanted stimulator module (RV-IPG) and a cortical-surface electrode array [1, 2, 3]
Manufacturer
明视脑机 (Mindtrix); founder and CEO Liu Bing, associate researcher at the Institute of Automation, Chinese Academy of Sciences; company founded 2024 [1, 3]
Interface class
Cortical-surface stimulating electrode array over visual cortex with wireless power and data through the scalp [1, 2]
Origin
Founder from the Chinese Academy of Sciences Institute of Automation; company founded 2024 [1]
First demonstrated
Announced in December 2025: visual percepts of complex shapes and colors in one patient, in an investigator-initiated study (company claim, reported by China Science Daily) [1, 4]
First human implant
The study patient had temporary therapeutic electrodes placed for occipital lobe epilepsy surgery; the team ran its stimulation study in the window after that implant [1]. Date unreported
Species studied
Human (one reported patient); non-human primate validation is listed as a research focus on the company site [1, 2]
Regulatory status
Investigator-initiated trial stage. The founder said the team plans type testing in 2026 and a registration trial for blind patients in 2028 [1]. No approval
Function
Converts camera images into electrical stimulation patterns on the visual cortex to produce light points, shapes and colors; includes recording and closed-loop modules [1, 2]
Target tissue
Primary visual cortex surface, per the system description [1, 2]

Value and source scope
Interface type
Soft, ultra-thin electrode array with small contacts attached to the visual cortex surface [1]

Notable demonstrations
China Science Daily, December 22, 2025: a patient reported colored points and simple shapes when the visual cortex was stimulated, with the eyes covered, in an investigator-initiated study. The patient was not fully blind [1]. Company announcement of ‘global first’ quantitative complex shape and color perception was reported by Science and Technology Daily on December 5, 2025 [3]
Clinical and preclinical evidence
Field
Value and source scope
Human subjects
One epilepsy patient with a largely intact visual pathway in the reported study [1]
Preclinical cohort
Follow-up duration
Indications
Vision loss from conditions such as retinitis pigmentosa, glaucoma and optic nerve injury, per the founder [1]
Trials and registries
Primary outcomes
Key limitations
One non-blind patient, temporary electrodes, no peer-reviewed report found, and company statements about the product electrode and implanted stimulator are not matched to the study hardware
Engineering tradeoffs
Field
Value and source scope
Strengths
Soft thin electrode lowers brain irritation per the team; bypasses eye and optic nerve problems [1]
Limitations
Percepts are described as points and simple shapes; blind-patient evidence does not yet exist [1]
Scaling constraints
Version boundary
The reported human result used therapeutic electrodes placed for epilepsy surgery and external stimulation. The company site’s 128-channel ECOG-RS electrode and RV-IPG module describe the intended product; whether they were used in the patient is not stated.
