Wireless Battery-Free Bioelectronics

Publication output: 14 peer-reviewed journal articles, 5 conference proceedings/abstracts, and 1 book chapter.

Mentored or managed 10+ researchers/students across graduate research work.

Biohub deck platform metrics: below 50 mg device weight, up to 2 m wireless power range, 5 months rapid-aging testing, and below 20 days recovery.

Validation infrastructure: 20+ test fixtures, 6 tuned antenna designs, and 3 simulation frameworks.

Platform details included 13.56 MHz magnetic resonant coupling, device operation testing greater than 1 year, and MRI/CT compatibility for post-operation probe-targeting analysis.

Subdermal photometry source-review metrics: approximately 10.5 mm × 7 mm platform size and approximately 27 Hz data streaming with 12-bit resolution.

Electrical neurostimulation source-review metrics: approximately 5.5 V compliance and approximately 18 mW wireless harvesting in relevant test conditions.

Osseosurface electronics source-review metrics: up to approximately 87 Hz communication with 14-bit resolution.

Why I built it

I wanted to build chronic sensing and stimulation platforms that worked without tethers or batteries.

What I built

Wireless photometry, neurostimulation, and osseosurface systems using flexible circuits, soft materials, and biocompatible encapsulation.

What worked

The strongest part was proving that tiny implantable systems could still harvest power, communicate, and operate chronically.

What failed

Implantable systems make every constraint harder: geometry, heating, encapsulation, and in vivo behavior all matter.

What I learned

Wireless implantable work is a good test of whether a system is actually engineered, not just assembled.
