Abstract

Harvesting energy from irregular/random mechanical actions in variable and uncontrollable environments is an effective approach for powering wireless mobile electronics to meet a wide range of applications in our daily life. Piezoelectric nanowires are robust and can be stimulated by tiny physical motions/disturbances over a range of frequencies. Here, we demonstrate the first chemical epitaxial growth of PbZr(x)Ti(1-x)O(3) (PZT) nanowire arrays at 230 °C and their application as high-output energy converters. The nanogenerators fabricated using a single array of PZT nanowires produce a peak output voltage of ~0.7 V, current density of 4 μA cm(-2) and an average power density of 2.8 mW cm(-3). The alternating current output of the nanogenerator is rectified, and the harvested energy is stored and later used to light up a commercial laser diode. This work demonstrates the feasibility of using nanogenerators for powering mobile and even personal microelectronics.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Existing energy-harvesting methods (thermoelectric, piezoelectric, biopotential, or glucose) are anatomically specific and yield power densities too low (<0.1 μW/mm2) for a microimplant.

    “However, these methods are anatomically specific and, in their existing forms, yield power densities too low (<0.1 μW/mm 2 ) for a microimplant.”

    From Wireless power transfer to deep-tissue microimplants (2014) · cites this paper as [5]

    The introductory passage following the Abstract says earlier piezoelectric nanogenerators produced too little power for conventional components. 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. The Discussion reports this paper’s generator output in mW/cm³, a different measure. (LLM, conf=0.85)

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.

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.
