An integrated Mg battery-powered iontophoresis patch for efficient and controllable transdermal drug delivery

Abstract

Wearable transdermal iontophoresis offers advantages for patient-comfort when deploying epidermal diseases treatments but current self-powered iontophoresis based on energy harvesters is limited in the support of efficient long-term operation therapeutic administration. Here, the authors propose a simplified wearable iontophoresis patch with a built-in Mg battery for efficient and controllable transdermal delivery.
