Wireless power transfer to deep-tissue microimplants
Open accessAbstract
Progress in semiconductor technology paved the way for devices at the scale of a millimeter or less (“microimplants”), but the miniaturization of the power source remains challenging. Although wireless powering has been demonstrated, energy transfer beyond superficial depths in tissue has so far been limited by large coils (at least a centimeter in diameter) unsuitable for a microimplant. Here, we show that this limitation can be overcome by a method, termed midfield powering, to create a high-energy density region deep in tissue. We demonstrate wireless power transfer to a millimeter-sized device implanted five centimeters inside the chest on the surface of the heart—a depth once thought out of reach for wireless power transmission.

Section 2 describes tissue-specific parameters for predicting dielectric behavior and introduces the Debye equation, but says the tissue spectrum is more appropriately described by multiple Cole-Cole dispersions. Section 3 says a four Cole-Cole model was adopted throughout the study. The citation is attached to the model description, not the subsequent 1.6 GHz efficiency finding. (LLM, conf=0.88)

It does not establish that thermoelectric, biopotential, or glucose-based methods are anatomically specific, nor does it give the <0.1 μW/mm² threshold or assess whether those methods can power a microimplant.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-11, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-11 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Cited sources are checked with a language model’s help (gpt-6-sol).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
