Chronic Biosymbiotic Electrophysiology 

Happy to share that our paper on Chronic Biosymbiotic Electrophysiology has been published in Advanced Functional Materials.

This work demonstrates the integration of conductive carbon-doped TPU into textiles for electrophysiological applications like ECG and impedance pneumography, and biosymbiotic devices for impedance myography. This approach eliminates the need for adhesives while maintaining high-fidelity, comparable to gel electrodes, the clinical gold standard. The textile integration ensures large area coverage with minimal motion artifacts, making it ideal for continuous ECG monitoring. Meanwhile, the biosymbiotic integration enables precise, localized interrogation, supporting advanced electrophysiological modes. The technology is, of course, integrated with our recharge at distance capabilities demonstrated in our prior work https://doi.org/10.1016/j.bios.2023.115218,https://doi.org/10.1126/sciadv.abj3269) which, combined, results in a multimodal electrophysiological platform that can operate 24/7 over many weeks without interruption or signal degradation.

Comprehensive overview of implantable organ interfaces 

Our comprehensive review article on Wireless Battery-free and Fully Implantable Organ Interfaces published in Chemical Reviews today.

The review covers all aspects of the technology class and features extensive statistics. 

Congratulations to Dr. Aman Bhatia, Tucker Stuart, Kevin Kasper, Jessica Hanna and David M. Clausen.

We also publish the data used in the statistics throughout the article, for everyone that wants to do further analysis

Biosymbiotic devices to combat the reduce digital health divide

In remote areas with limited connectivity, effective patient monitoring remains a challenge, often resulting in substantial healthcare disparities. In our most recent work we tackle the challenge with a seamless wearable device enabling long-range transmission of biosignals over 15 miles, integration of on-board biosignal computation, and remote wireless recharging to enable weeks of continuous operation.

Interested in a deep dive on the technology, find the article published in PNAS. For the quick read, check out the short media article.

Next-Gen Nervous System Interfaces for Spinal Cord Function Recovery and Gait Restoration 

The next generation of nervous system interfaces is in the starting blocks, promising to recover spinal cord functions and make the paralyzed walk again. However, interfacing with this very mobile area of the body is tricky. In our newest work, we solve prevalent technological challenges to create seamless untethered interfaces with the spinal cord and muscles, demonstrating restoration of gait over weeks. 

Ever wondered how we can make wearables that work 24/7 without needing to plug in or use a wireless charging pad?

Check out our newest paper in collaboration with Christophe Fumeaux`s lab that dives deep into Biosymbiotic wearable antenna design for wireless power casting.

Work on context aware antenna design published in Biosensors and Bioelectronics

Check out our most recent work on behavior guided antenna design for wearables. With this design method, we demonstrate that you can recharge a wearable with a simple powercasting box on your table and transfer sufficient energy to run high fidelity and high sampling rate biosignals acquisition for weeks without touching the device.
