Iontophoresis is a process used to deliver a specially formulated, transdermal medication for the body through skin. This transdermal medication is a charged compound driven through the skin by the flow of electrical current. For some diseases and conditions, this method of drug delivery has significant advantages for many patients over oral, hypodermic or topical medications.

Some of the biggest challenges that designers face when creating devices such as iontophoresis patches are that the critical electronics are in the wearable portion of the device, which is meant to be used once then thrown away. This scenario creates intense pressure for the patch electronics to be small and for lower overall BOM costs. Also, since this is a small, disposable item, battery cost and energy capacity impose further constraints on the design. Finally, the design needs to be easily modified for additional features, such as changes in the medication dose and duration. Medical device designers can use our components to create safe, cost-effective iontophoresis device designs.
