Adhesives: Part of the Future for the Remote Monitoring Sensors?

I just ran across this article a few minutes ago. It's a serious article published in Machine Design. Here's the link: http://www.machinedesign.com/mechanical/adhesives-enabling-future-wearable-medical-devices?NL=MD-005&Issue=MD-005_20180724_MD-005_524&sfvc4enews=42&cl=article_1_b&utm_rid=CPG05000003255032&utm_campaign=18775&utm_medium=email&elq2=5b76b40ea8f44d76b2b883c5c09f23fe

It's an extremely readable article and what's being described has in my opinion real applicability in the future of medical sensors. Adhesive, "band-aid" or strip sensors development applies to both the fitness set as well as to remotely monitored patients.

Transmitting data to monitoring systems and people will likely require an intermediate device such as a smart phone. I suspect that the real issues and hurdles will likely revolve around digital communications issues and standardization. Having worked most of my life in the communications domain, communications issues can be successfully overcome.

Here are a few quotes from the article:

Device manufacturers are taking steps to create medical devices that are smaller, lighter, and less invasive. Whether they’re adhering device components together or sticking a device to skin, adhesives are uniquely bonded to a device’s success.

Both consumers and patients want wearable devices to be smaller, lighter and less cumbersome to use for seamless integration into their everyday lives. The design process can get challenging when devices must maintain accurate sensing capabilities, but also reduce friction to ensure precise data collection. Adhesives can help to keep friction to a minimum by being breathable and maintaining a low profile. In addition, options with flex electronics, as well as addressing battery implications and electromagnetic interference, provide opportunities for advancement.

Adhesive wear time is a crucial consideration when designing a wearable device, impacting overall resilience and durability, as well as how often the user will need to change their device. 


I should mention that by the looks of things, it appears to me that 3M maybe behind the article. Nevertheless, I think that considering adhesives in the research, design and development process of a bio-sensor is worth your time.
