B-CRATOS OBJECTIVES
Improve healthcare, quality-of-life, learning and cognition
The technology developed by B-CRATOS will have profound effects in several fields. In neuroprosthetics it bypasses damaged circuits in order to restore missing biological functions. It will also impact electroceuticals (modulation of organ function through neural circuits instead of pharmaceuticals), Brain-Computer Interfaces (brain plasticity through machine learning) gaming (immersion), and Virtual Reality.
The B-CRATOS system features a battery-less, fully-implantable brain interface capable of sensing high-resolution neural signals and precisely stimulating cortical targets. The Blackrock Microsystems Utah Array is connected to a small biocompatible, hermetically-sealed implant containing custom electronics to detect, amplify, and digitize neuronal activity and deliver electrical stimulation. A wearable external module designed bv NTNU researchers uses a novel wireless transmission technique to enable two-way wireless communications for high data rate transfer and stimulation control and to power the implant.
Fat intra-body communication (FAT-IBC) is based on microwave propagation confined to the subdermal body fat with minimal interference from external electronic devices.

Machine learning (ML) and deep learning (DL) algorithms for arm control and sensor stimulation will be implemented for pattern recognition and classification

Most electronic skins (ES) suffer from high power consumption and low spatial resolution. The B-CRATOS sensory system will employ a novel combination of triboelectric nanogenerators (TENGs) and graphene-based hydrogels to provide a time-dependent force map in digital format. TENGs harvest mechanical energy when touched eliminating the need for an external power supply.
