Biosignal Hardware Architecture for Research Systems
Delivered a flexible hardware architecture that allows researchers to scale biosignal acquisition systems from entry-level to advanced multi-channel configurations without system replacement.
Situation
Existing biosensing systems are typically monolithic and expensive, requiring full system replacement to increase channel count or capabilities. This limited experimentation and iterative research workflows.
Solution
Engineered a modular hardware platform composed of interoperable sensing units. This modularity enabled users to incrementally scale their systems based on evolving research needs.
