Foldable Wireless Multimodal Microneedle Drug Delivery System (fMMD): Design and Application
2025-02-25
Researchers have developed a foldable wireless multimodal microneedle drug delivery system (fMMD) integrating electrocardiography (ECG), photoplethysmography (PPG), and drug delivery functionalities. The fMMD features a serpentine interconnect island-bridge design for flexibility and stretchability, enabling conformal skin contact. Wireless data transmission is achieved via Bluetooth Low Energy (BLE), allowing for closed-loop feedback control by triggering drug release based on physiological signals such as heart rate. The system demonstrates promising performance in multimodal monitoring and drug delivery, holding potential for cardiovascular disease diagnosis and treatment.
