A new device, pioneered by Anqi Zhang, can record brain activity without harming neural tissue, using the passageways of blood vessels. This innovation overcomes previous limitations, enabling precise recording from individual neurons in living animals.
Scientists have developed a multi-layer, thin film sensor that automatically realigns during healing, mimicking human skin's layered structure. The material, comprising PPG and PDMS polymers, can self-heal and restore functionality without human input or effort.
Researchers developed a wireless smart bandage that speeds up tissue repair, increases new blood flow, and enhances skin recovery by reducing scar formation. The device promotes faster closure of wounds and reduces infection risk through real-time biosensor data and electrical stimulation.
