Multifunctional Förster Resonance Energy Transfer Materials as Thermo‐ and Mechanochromic Time Integrators

open access: yesAdvanced Optical Materials, EarlyView.
Multifunctional fluorescent coatings offering simultaneous thermo‐ and mechanochromic‐time integration via Förster resonance energy transfer (FRET) are reported. The exchange of fluorophores among donor and acceptor droplets in the coatings over time results in a decrease in the average intermolecular distance between the donor–acceptor pair, yielding ...

Boosting the Magnetic Response of a Composite Nanostructure in the Near‐Visible Region with a Fano Resonance

open access: yesAdvanced Photonics Research, EarlyView.
Optical simulations of composite plasmonic split‐ring resonators show that a magnetic response can be obtained at wavelengths near the visible regime. The response is further increased by extending the geometry and enabling a Fano resonance through the coupling of magnetic dipoles.

The Future of Research in Cognitive Robotics: Foundation Models or Developmental Cognitive Models?

open access: yesAdvanced Robotics Research, EarlyView.
Research in cognitive robotics founded on principles of developmental psychology and enactive cognitive science would yield what we seek in autonomous robots: the ability to perceive its environment, learn from experience, anticipate the outcome of events, act to pursue goals, and adapt to changing circumstances without resorting to training with ...

A Compact Optical Sensor to Self‐Assess Skin Health after Sun Exposure

open access: yesAdvanced Sensor Research, EarlyView.
This work presents a portable, low‐cost device capable of detecting changes in the skin associated with excessive sun exposure through reflectance measurements. In vitro validation experiments in skin‐mimicking tissue phantoms showed the device can detect relative pigmentation changes as small as 5%.

Electronic Nose for Indoor Mold Detection and Identification

open access: yesAdvanced Sensor Research, EarlyView.
This study explores the potential of a SnO2 nanowire‐based chemiresistive electronic nose not only to detect but also to identify two common indoor mold species, Stachybotrys chartarum and Chaetomium globosum on two different growth substrates. In a laboratory setup, the electronic nose displays high classification performance using optimized linear ...
