Graphene rippling is the formation of nanoscale waves, wrinkles, and corrugations in a graphene sheet. Those shape changes are not just a curiosity: they can alter how graphene conducts heat and electricity, how it interacts with other materials, and whether it performs consistently in sensors, coatings, and electronics.
Oregon State University researchers reported an electrochemical sensor that uses reduced graphene oxide in a nanocomposite designed to speed up food-quality testing. The device was built to detect theobromine in drinks and chocolate milk, pointing to a practical route for lower-cost screening outside conventional labs.
MIT.nano’s 2026 START.nano cohort includes a startup developing nanomaterial-based ion detectors for analytical, chemical and radiation instruments, a sign that a niche sensing platform is moving closer to commercial use.
A new Nature Sensors study published on March 31, 2026, describes a self-powered chemical sensor built around graphene, MoS2 and silicon, a design aimed at lowering power demands in compact sensing devices.
Researchers at the University of Arkansas and the University of Michigan say they have demonstrated the first ultra-low-power temperature sensor powered by graphene-based solar cells, a battery-free design that could reduce maintenance in remote monitoring and wearable devices.
Melexis and Graphenea have expanded their graphene biosensor collaboration with a development kit for evaluating integrated GFET-on-CMOS sensors, a practical step toward chip-scale biosensing systems.
