Selected facts

Quantitative details and source-backed proof points.

Nature Communications 2021 publication: thin, wireless, battery-free, multimodal osseosurface electronics.

Communication/readout metric: up to approximately 87 Hz with 14-bit resolution.

Multimodal sensing included strain plus temperature/physiological sensing.

Engineering constraints included bone curvature, soft tissue, encapsulation, surgical handling, and sensor-to-bone coupling.

Validation included strain/sensor characterization, antenna/power behavior, device handling, packaging, and preclinical workflows.

Project summary

Why it exists, what I built, and what I learned.

Why I built it

Musculoskeletal monitoring needed thin, conformal electronics that could interface with bone and surrounding tissue without bulky batteries or tethers.

What I built

Osseosurface-compatible mechanics, strain/physiological sensing, wireless power, wireless readout, flexible packaging, and preclinical validation workflows.

What worked

The device connected thin mechanical design, sensor placement, wireless readout, encapsulation, and bone-interface coupling into one biointerface.

What failed

Bone curvature, soft tissue, encapsulation, surgical handling, and sensor-to-bone coupling all constrained the device design.

What I learned

Mechanical interface design is central to implantable sensing when the target is a moving biological structure.
