New generation high-throughput flexible brain computer interface platform

bciflex Wireless Implantable Signal Acquisition System

The bciflex Wireless Implantable Signal Acquisition System is a new generation of brain computer interface product that uses flexible electrode technology. It consists of implantable signal acquisition devices and neural signal acquisition and decoding software, which can real-time collect brain activity signals and "translate" these signals into text or control instructions through algorithms, helping patients rebuild language and motor functions, gradually improving their independence and quality of life, and enabling every patient to reconnect with the world through their thoughts.

Ultra thin flexible electrode

The R&D team of bciflex Medical has been deeply involved in the research of flexible electrode materials for decades. The team's independently developed invasive high-throughput flexible electrode has obtained patent authorizations from both China and the United States.
  • Ultra thin and flexible

    Micron level thickness, only a fraction of a human hair, with a small proportion in the brain; Using flexible materials that closely adhere to brain tissue; Excellent biocompatibility.

  • Anti-fall design

    The unique anti drop electrode design allows the electrode to pulse with the brain, effectively preventing relative movement between the electrode and brain tissue, and achieving long-term stable collection of neural signals.

Implantable signal collector

  • bciflex Medical implantable signal collector, suitable for patients' real daily use scenarios; Adopting a fully implanted design effectively avoids the risk of infection caused by open wounds; Built in rechargeable battery, charged through an external wireless induction charger (the battery has successfully passed the IEC62133 international safety standard certification).

Electroencephalography algorithm

On the algorithm side, bciflex Medical adopts its self-developed deep neural network algorithm to achieve real-time decoding of high-throughput EEG signals online. At the same time, an adaptive network is adopted to achieve online automatic updating of the model, further improving decoding accuracy and algorithm generality.
On the data side, bciflex Medical has built a high-precision EEG data platform with over 60T of animal neuron EEG data and dozens of T of human deep brain neuron EEG data. Based on the existing massive EEG data, bciflex pre trains neural EEG models to accelerate model training speed, improve decoding model universality and EEG decoding accuracy, and support more clinical scenarios.
  • high precision

    2D motion trajectory decoding, with an average trajectory error in millimeters; The accuracy of pure brain controlled experiments is close to 100%.

  • High real-time performance

    The high channel decoding algorithm takes about 1 ms, which is 100 times faster than traditional algorithms; In pure brain controlled experiments, the completion time of motor imagery paradigm is 37% faster than natural hand movements.

  • high versatility

    Adapt to multiple paradigms and support different clinical scenarios; The model supports rapid adaptation across days and individuals.

Electrode implantation robot

In order to maximize the clinical value of high-throughput invasive flexible brain computer interfaces and ensure the precision, intelligence, and efficiency of electrode implantation processes, bciflex Medical has developed an electrode implantation robot aimed at addressing key challenges for future large-scale clinical applications.
  • precise

    A high-precision operation and control platform based on "visual servoing" technology, equipped with multiple sets of high-definition cameras, to achieve fast and accurate target positioning. Combined with intelligent operation control algorithms, its positioning accuracy can reach the cellular level.

  • intelligence

    Automatically plan the position and depth of electrode implantation, intelligently avoid dangerous areas such as blood vessels, and achieve full process intelligence and automation of electrode implantation.

  • efficient

    The implantation time of a single electrode wire is less than 30 seconds, and multiple electrode wires can be continuously implanted. Within half an hour, the implantation of a thousand channel electrode can be completed, greatly improving surgical efficiency.
