Wireless power – critical equipment

The advantages of having medical equipment readily available without the need to find power outlets include the ability to improve the ease of moving instruments, avoidance of accidental unplugging of critical equipment, reduced risk of electrical shock, and reduction in the potential for bacteria to breed. The emerging availability of wireless power is making wireless medical carts and bedside units a reality. In addition to the convenience, wireless power will increase safety and reduce the price by removing cable clutter around the patient.

Wireless power – patient care

In addition to untethering the instruments in the hospital, wireless power enables patients to be more comfortable while bedridden and increases their freedom of movement when ambulatory.

Wireless power can be used for efficient and speed recharging of electric wheelchairs. There are also numerous direct patient applications for wireless power transfer enabled by GaN technology. Some of the high-impact applications under development and in clinical trials include applications that involve heart monitors and nerve stimulators that do not require that wires, that can be prone to infection, protrude from the body. Wireless power is not only more convenient; it is safer for the patient.

Wireless power – health & fitness trackers

Wearable health & fitness trackers have become ubiquitous in recent years. The need to easily and efficiently keep these devices charged has led many companies to move to a wireless power solution for added consumer convenience.

Gallium nitride (GaN)-based FETs and ICs are particularly suitable for wireless power applications due to their ability to operate efficiently at high frequency, deliver high power, and in a small, low-profile footprint.
