Wireless powering (or WPT – Wireless Power Transfer) is becoming increasingly popular in miniaturised medical applications. Electromagnetic power transfer uses a contactless link between 2 coils to transfer electrical energy. Implants using this type of power transfer can include a rechargeable or a primary battery or have no internal power source at all. In the latter case, only activity-on-demand (such as measurements, stimulation, …) can take place. ICsense has designed several custom ASICs exploiting the use of WPT in accordance with ISO13485 medical standards. Read more.
