- Invasive BCIs: Involve surgical implantation of electrodes directly into the brain. These offer much higher precision and bandwidth, crucial for restoring motor function in paralyzed individuals (e.g., controlling robotic limbs or computer cursors with thought) or potentially for cognitive enhancement.
- Neural Dust/Arrays: Miniaturized, wireless sensors designed for long-term implantation to monitor or stimulate neural activity.
Advanced Prosthetics & Exoskeletons
Beyond traditional prosthetics, this field focuses on restoring and enhancing physical mobility and capability.
- Bionic Prosthetics: Advanced artificial limbs with sensors that interact with residual nerves and muscles, allowing for more natural control and even tactile feedback (e.g., feeling pressure or temperature).
- Exoskeletons: Wearable robotic frameworks that enhance human strength, endurance, or provide mobility for individuals with paralysis. They are used in industrial settings for heavy lifting, rehabilitation, and military applications.
Augmented and Virtual Reality (AR/VR) for Augmentation
While also a separate Deep Tech field, XR plays a significant role in human augmentation by changing our perception of reality and interaction.
