System Architecture for Wireless-Charging Hospital Carts

The challenge

Hospital carts carry equipment and supplies around wards all day, and most are charged through power cords. Those cords create trip hazards and make carts harder to keep clean, which matters for infection control.

What we did

We analyzed the carts' power requirements and the layout of the hospital to set the electrical and mechanical requirements for a charging system. We then designed the system and selected components so it would be efficient, reliable and compatible with the medical equipment the carts carry. We also brokered a partnership between the cart manufacturer and a wireless charging provider, which brought discounted hardware and software for managing the cart fleet. This work spans our IoT and embedded systems services.

The result

Nurses in the pilot studies praised the carts' ease of use, safety and cleanliness. The design is ready to move from development to production, with testing planned in large hospitals.
