Biodegradable RF Metamaterial Perfect Absorber for Wireless Soil pH Monitoring

open access: yesAdvanced Materials Technologies, Volume 10, Issue 8, April 17, 2025.
This study proposes a wireless soil pH sensor using a sheet‐type perfect absorber metamaterial. This sensor has a uniform water‐soluble Mg film at the bottom coated with hydroxyapatite that degrades depending on the pH, and a periodic square split ring resonator metamaterial structure made on top of a lossy dielectric plate.

Polydiacetylene‐Crosslinked Oligosiloxanes for Dual‐Mode Temperature Sensing

open access: yesAdvanced Materials Technologies, Volume 10, Issue 8, April 17, 2025.
This work combines polydiacetylenes with oligosiloxanes for enhanced solubility and processability. The hybrid material showcases reversible thermochromism (25–47 °C) and dual‐mode temperature sensing via color shifts and capacitance changes. With improved properties, this work paves the way for scalable optoelectronic flexible and conformable sensors.

Photonic Crystal Enhanced Microscopy on a 2D Photonic Crystal Surface

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
This work demonstrates the design, fabrication, and the first‐time test of a 2D photonic crystal surface for photonic resonator absorption microscopy. The designed surface uniformly enhances electromagnetic near fields, achieving > 100% improved detecting uniformity for surface‐captured AuNPs from a blocking biosensor assay aimed for detecting SARS‐CoV‐
