Machine-Readable Pattern for Colorimetric Sensor Interrogation [PDF]
EUROSENSORS 2018, 2018 We present a systematic methodology to generate machine-readable patterns embodying all the elements needed to carry out colorimetric measurements with conventional color cameras in an automated, robust and accurate manner. Our approach relies on the well-stablished machine-readable features of the QR Codes, to detect the pattern, identify the color ...

Advanced Engineering Materials, EarlyView.This study proposes a potential device design for joint cartilage replacement. Silica‐polytetrahydrofuran (SiO2‐PolyTHF) hybrids with customizable mechanical properties were developed to mimic the characteristics of a natural meniscus. These were synthesized through a two‐pot sol–gel hybrid process.

From Food to Power: Hydrogel Thermoelectrics for Ingestible Electronics
Advanced Functional Materials, EarlyView.We introduce a fully edible thermoelectric–electrochromic platform that harvests heat from food and converts it into a visible color change. N‐type and p‐type hydrogel thermoelectric generators connected in series power anthocyanin‐based electrochromic displays, demonstrating the feasibility of safe, biodegradable, ingestible systems for on‐food ...

Counterion free colorimetric metal cation sensor array
, 2019 By a systematic ionic effect study in colorimetric dye arrays, we effectively suppressed the anion effect using the proper buffer condition and configured a universal cation sensor system. This result cast a warning for careful validation for other anion
