Abstract

Means for high-density multiparametric physiological mapping and stimulation are critically important in both basic and clinical cardiology. Current conformal electronic systems are essentially 2D sheets, which cannot cover the full epicardial surface or maintain reliable contact for chronic use without sutures or adhesives. Here we create 3D elastic membranes shaped precisely to match the epicardium of the heart via the use of 3D printing, as a platform for deformable arrays of multifunctional sensors, electronic and optoelectronic components. Such integumentary devices completely envelop the heart, in a form-fitting manner, and possess inherent elasticity, providing a mechanically stable biotic/abiotic interface during normal cardiac cycles. Component examples range from actuators for electrical, thermal and optical stimulation, to sensors for pH, temperature and mechanical strain. The semiconductor materials include silicon, gallium arsenide and gallium nitride, co-integrated with metals, metal oxides and polymers, to provide these and other operational capabilities. Ex vivo physiological experiments demonstrate various functions and methodological possibilities for cardiac research and therapy. Tools for cardiac physiological mapping are important for basic and clinical cardiac research. Here the authors use 3D printing to create a thin, elastic silicone sheath that fits tightly around the entire epicardium and contains sensors to measure a variety of physiological parameters of the beating heart ex vivo.

  • Resistive metallic temperature sensors and thermistors are the most commonly used sensors in flexible thermal electronics.

    “Resistive metallic temperature sensors[207] and thermistors[208] are the most commonly used sensors in flexible thermal electronics.”

    From Flexible Electronics and Devices as Human–Machine Interfaces for Medical Robotics (2022) · cites this paper as [207]

    The Design and fabrication section identifies gold serpentine resistors as temperature sensors, and Spatiotemporal cardiac measurements and stimulation explains that their resistance changes with temperature. This supports the cited example of a metallic resistive temperature sensor, but the paper does not establish that such sensors are among the most commonly used in flexible thermal electronics.

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.
