Today, connected medical devices are transforming the way care is delivered. Wearables, home monitors, and other networked devices that rely on machine-to-machine communication offer compelling solutions to tough healthcare challenges:

  • Improving prevention, early detection and outcomes.

  • Reducing the cost and effort of delivering care.

  • Relieving shortages of primary care and specialist providers.

  • Serving patients in rural, remote or developing areas.

  • Helping the elderly age in place.

  • Managing chronic diseases.

  • Giving patients greater control over their health.

To create the next wave of connected healthcare devices, designers need the right materials. Depending on the type of device and usage scenario, advanced polymers may be required to increase ergonomics and usability, provide an attractive appearance, support miniaturization, ensure biocompatibility, deliver flame retardance and heat resistance, and stand up to chemical cleaners and wear and tear.

Defining Progress

The National Cancer Institute at the National Institutes of Health defines connected health as “the use of technology to facilitate the efficient and effective collection, flow and use of health information.” Technology is transforming care delivery by making it simpler, easier, more collaborative, and more data driven.

Digital technologies that are the foundation of connected health include:

  • Sensors: worn on/adhered to the body or implanted to identify, capture and measure data.

  • Internet of Medical Things (IoMT): connects smart sensors and devices to each other and the cloud. As a subset of the IoT, this connected system of medical devices and applications provides collected data to healthcare IT systems through computer networks.

  • Wireless connectivity: rapidly transmits data over the network.

  • Mobile devices and applications: collect and transmit data for building reports on individuals or public health trends.

  • Videoconferencing platforms: support telehealth systems.

  • Big Data analytics: mines and analyzes data from IoT devices.

  • Cloud computing: scales easily to handle huge data volumes.


By 2025, the United States is expected to face a shortage of:

  • 446,300 home health aides

  • 95,000 nursing assistants

  • 29,400 nurse practitioners

Categories Defined

It's a large universe, but the connected health sector can be divided into just a few manageable categories:

  • On-body segment: Includes consumer wearable devices for tracking health and fitness, and clinical wearables that are typically approved for use by regulators and used under the supervision of a physician.

  • In-home segment: Includes personal emergency response systems, remote patient monitoring and telehealth virtual visits.

  • Community segment: Examples are kiosks that dispense information, point-of-care devices used outside the home or healthcare setting, and mobility services that track a patient's health parameters during transit.

  • In-clinic segment: Includes devices used for administrative or clinical functions in a clinic, via telehealth or remotely.

  • In-hospital segment: Includes wearable devices for patients and facility management applications, such as hand hygiene monitoring for staff and environmental controls.

Tech That Heals

In addition to digital technology, the connected health megatrend owes its adoption and growth to the urgent need for fresh approaches to these persistent challenges:

  • Improving adherence and outcomes. Medical treatment today still relies heavily on qualitative information and doctor/patient conversations. To improve public health, there is a need for vast quantities of data that can be analyzed to identify trends with high confidence and accuracy. On an individual level, nonadherence to prescribed medication is a major contributor to poor outcomes. It can be addressed, in part, through technology that reminds patients to take their meds.

  • Expanding care delivery while controlling costs. Providing in-person healthcare to people in underserved areas, such as rural communities and developing nations, and to home-bound, elderly or disabled patients, is expensive, inefficient and time-consuming. Plus, there's a looming shortage of primary care and specialist physicians and other healthcare professionals — just as demand from the aging population is rising.

  • Helping the elderly age in place. Most older people want to remain in their homes as long as possible. However, dementia, physical frailty, and other health issues can interfere with independent living and lead to costly hospitalizations and nursing home admissions.

  • Managing chronic conditions more effectively. Chronic conditions, such as diabetes, hypertension and chronic obstructive pulmonary disease (COPD), require ongoing monitoring and management that can place a heavy burden on clinicians and patients alike. Inadequate management can lead to patient noncompliance and costly hospital admissions.

  • Increasing patients’ involvement in their health. Although many people still defer to their doctors, the Wall Street Journal reported that quality gaps in U.S. healthcare and rising death rates from many diseases highlight the need for patients to play an active role in getting the best care and avoiding harm. Providers are encouraging patients to manage chronic conditions proactively and help make informed treatment decisions.

Generational Change

Millennials are often called the “C” (for connected) generation. As the largest generation (80 million strong), these young people are helping to advance connected health through their familiarity with technology, including mobile devices and apps. This generation of patients are looking for innovations in how they connect with providers and share information. Millennials tend to choose:

  • Health advice and support from social media vs. institutions, clinicians, or manufacturers.

  • Employers that offer fitness benefits.

  • Alternative therapies, natural foods, and supplements vs. pharmaceuticals.

  • Companies that emphasize sustainability.

Cell Phone Connections

Most people around the world are able to rent or own a cell phone. In countries where access to healthcare is a problem — whether due to lack of clinicians or poor infrastructure — mobile healthcare is bridging the gap. Even where there is no electricity, a cell phone signal can connect patients and providers. Examples include:

  • Sending out SMS messages about health education, appointment and medication reminders, and information about medical services

  • Sending images of patient conditions (skin rashes, tissue samples) for evaluation by experts.

Devices for off-the-grid healthcare. Areas with intermittent or no electricity can benefit from these innovative devices:

  • Cell phone microscope — this addon turns a mobile phone camera into a microscope.

  • Solar blood pressure monitor — this semiautomatic upper-arm blood pressure device uses solar-charged batteries.

  • Smartphone ultrasound — this device uses a transducer plugged into a smartphone, along with a software package, to create an ultrasound machine.
