Energy-efficient health patch to improve mobile health solutions

A key building block in the pursuit of improved and more accurate mobile health solutions, the patch is available for licensing by partner companies ready to initiate their own medical applications.

“Since our entry in this space, we’ve advanced far beyond proof-of-concept to a patch that has attained a high level of technical maturity,” said Ruben de Francisco, Program Manager Wearable Health at imec and Holst Centre, “The underlying technologies have been fully validated, and the patch itself has been tested within a controlled environment. Today, it is ready for preclinical and usability studies. Looking ahead, we plan to build on our expertise in the domain of data science to lay the foundation for a powerful patient management solution that not only captures data, but that also turns data into meaningful information upon which people and health providers can act.”

With more people living longer than ever before and chronic disease on the rise, traditional healthcare systems are being pushed to their limits. It is generally acknowledged that the concept of digital health, and specifically mobile health, can help address that issue by enabling individuals to better track and manage their health and receive personalised and optimised treatments while reducing medical inefficiencies and costs.

The health industry has recognised the challenges and solutions, with analysts predicting that the value of the global mobile health market is expected to more than triple in the next few years, from $19.2bn in 2016 to $58.8bn by 2020.

However, for mobile health solutions to be successful beyond concept, easy-to-use and accurate building blocks are required; technology that is being developed by imec, Holst Centre and TNO as part of their Wearable Health program. Their R&D on mobile health drives innovation from an application perspective, at system level and in terms of individual components – such as read-out circuits, batteries, adhesives, etc.

The health patch from imec, Holst Centre and TNO features more functionalities than any other patch, and does so in a small form-factor. At its heart is a chip that has been optimised for low power consumption. This chip is combined with a highly comfortable to wear electrode patch that can stay on the body for long periods of time, including when showering. It is the first patch to combine a variety of sensing capabilities – ranging from an accelerometer (to track a person’s physical activity) to ECG tracking (measuring the heart's electrical activity) and bioelectrical impedance monitoring (measuring body composition, respiratory activity and the distribution of body fluids).

“Many companies working in the digital health realm have great ideas for innovative solutions that could make it easier to remotely monitor people suffering from heart and respiratory diseases, to give an example. However, what is typically lacking, are the devices on which to run these solutions,” commented Chris Van Hoof, Program Director Wearable Health at imec and Holst Centre. “When collaborating with Holst Centre, we help these companies to take the next steps, from concept to device, and our health patch is one of the many vehicles available for licensing and customised product development,” added Jeroen van de Brand, Director flexible electronics at Holst Centre/TNO.

The health patch integrates technologies and components from industrial partners, including Hitachi Maxell’s batteries optimised for wearables, Shinko Electric Industries’ SiP (System in Package) miniaturisation technology and Henkel’s adhesive and ink technology.
