Many implantable bioelectronic systems require a high channel count throughput for electrical stimulation or recording of biopotential signals. Our current high channel recording and stimulating module design relies on an eight-contact linear connector, which can be stacked to achieve higher channel counts. However, this physically limits available channels. Instead, we are developing a modular 16-channel connection to be incorporated into a fully-networked module, allowing for multiple HIVE modules within a single system.

The remote modules of the COSMIIC System platform are sized to fit in the torso, legs, and arms of an average-sized adult, but they are too large to be placed in the hands, feet, or directly on organs. The SWARM Module is designed to address this limitation, and consists of a module adaptable to a variety of sensors with placement based on clinical need and targeted function. Potential applications could measure foot and hand movement; support feedback control for gait, balance, hand positioning and object manipulation; or form part of an implanted system regulating autonomic function in the heart, lungs, stomach, or other organs.

The therapeutic effect of Kilohertz frequency alternating current (KHFAC) is complex and multimodal, often resulting in suboptimal results due to improperly tuned waveform parameters.  But the ability to use electrical waveforms to both up-regulate and down-regulate the nervous system creates the possibility of COSMIIC users operating with greater autonomy, accuracy and control over their own physiological parameters. Additionally, adding an electrical nerve block to a system that already has electrical stimulation will allow researchers to incorporate reversible electrical nerve block via KHFAC into their research in a practical, effective, and safe manner.

We are developing an external wireless link that facilitates communication between the implanted COSMIIC Power Module and external sensors utilizing common wired (USB, I2C, SPI, CAN) and wireless (WiFi, ZigBee, ANT) protocols. This innovation will enable researchers to make use of off-the-shelf technology or purpose-built systems to act as inputs/outputs to the implanted COSMIIC System – lowering costs and risks while enhancing function.
