Wireless charging technology, which was once considered a futuristic innovation, is now a reality. This technology will enable a new generation of medical wearables and can streamline the sterilization and charging process for many portable, handheld or cart-based medical devices.
By eliminating the need for removable batteries or wired chargers, we can design medical devices to be hermetically sealed, with smooth surfaces which are not interrupted by connectors or battery compartment doors. Consequently, it is easier to sterilize such devices, and they are less prone to failures associated with repeated battery replacement and connector insertion. Such devices can therefore be more easily charged without using multiple charging cords and cradles.
Humavox’s RF energy is one of the effective methods for the wireless charging of medical devices. Unlike other technologies, it has the ability to integrate a wireless charging receiver into small devices and has advantages in product design, usability, and reliability.
RF is now being used to recharge the batteries in implanted transcutaneous electrical nerve stimulation (TENS) devices and pacemakers. The patient sits in a chair that contains a low-frequency RF source whose output is then received, rectified and stored by the device. Using RF harvesting, we can charge low-power medical devices like wearable devices, which can warn the patients against potential diseases and symptoms.
Wireless charging for medical devices has undoubtedly taken the application of these devices to a new level and paved the way for a bright and promising future. This field is therefore under continuous research and experimentation with a very promising future.
