Bouquet Fiber-based Neural Probe
THE PROBLEM
Neural probes are the key to unlocking the brain’s mysteries, yet current designs remain woefully inadequate. Most cutting-edge probes rely on outdated tip-based interactions, offering only a narrow, fragmented view of neural activity while leaving vast brain regions unexplored. Bulky, rigid structures provoke inflammation and tissue...

Biocompatible Strain Sensing Polymer Fiber
THE CHALLENGE
Strain sensing has large implications in biomedical applications to monitor wearer’s physiological conditions. Current metal or silicon based strain sensors cannot sense small deformations (less than 5%) & are not biocompatible, thus are not suitable for human health monitoring. These strain sensors are usually not very flexible...
