Podimetrics™

Early Ulcer Detecting Smart Mat

Case Study

THE PODIMETRICS MAT™

The Problem

Foot ulcers have a high probability of infection and are a leading cause of amputations among diabetes patients, making it one of the most expensive complications in medicine.

The Solution

Smithwise and Podimetrics collaborated to develop a smart, connected foot mat using a Remote Temperature Monitoring System™. It is a preventative technology to avoid the high cost and mortality associated with foot ulcers. The Podimetrics Mat™ can detect increases in temperatures around the foot, which precede the formation of ulcers. Typically ulcers are diagnosed only after an open sore has developed. With Podimetrics’ infrared temperature monitoring, patients can step on the smart mat in their own homes and it will alert their physicians if the mat identifies areas that are hotter than other areas. This allows for simple, brief and preventative interventions.

Smithwise collaborated with Podimetrics through
mechanical, electrical and software engineering
activities.

The mechanical design process included packaging of
electronics, development of the mechanical chassis, and
integration of removable soft-goods. By selecting the
appropriate production materials and processes, Smithwise ensured that the product met design for manufacturing & assembly (DFMA) requirements. A comprehensive production documentation package was created to facilitate the transfer from design into manufacturing.

Smithwise and Podimetrics collaborated to develop prototypes for clinical evaluation of a Smart Mat, a part of the Podimetrics Remote Temperature Monitoring System. 

Several electrical prototypes were developed throughout the process to evaluate the thermistor array, which is the critical system for identifying “hot spots” on the sole of a user’s foot. Smithwise developed firmware to drive the electronics and wirelessly communicate data from the smart mat to the cloud. 

The Podimetrics Mat™ is currently in more than 500 homes. In a recent study the mat detected more than 97 percent of developing ulcers before they were diagnosed at the doctor’s office.
