Today’s electronic devices, especially worn on the body, are small, lightweight, and mostly powered by batteries and regulated by low-quiescent-current (Iq) power converters. Such devices as cardiac monitoring patches, continuous glucose monitors (CGMs), insulin therapy patch pumps, and various biosensors rely on very low Iq, which will greatly extend the life of the batteries.

Some really incredible medical devices that feature low-Iq designs include:

• 3M Prevena Plus Duo Incision Management System with 3M Prevena Peel and Place Dressing
• Wireless, medical wearable ECG, SpO₂, PTT, and heart-rate monitors are operated using a single CR3032 battery and provide a battery life of 30 days
