A Mini‐Patch Magnetic Insulin Pump for Enhanced Delivery Resolution and Accuracy
Advanced Intelligent Systems, EarlyView.A miniaturized, high‐resolution magnetic insulin pump is developed by proposing a unique magnetic pumping mechanism, where insulin dispensing is achieved through a magnetic soft actuator that directly compresses the insulin chamber. The device occupies less than one‐quarter the size of piston‐based pumps and allows for a 0.01 μL delivery resolution ...
