Enabling Wearable & Wireless Technologies for Mobile & Digital Health

Realizing the promises of Digital Health means incorporating key technologies seamlessly and with reliable operation. DeviceLab is proficient in the implementation of these key technologies, including Bluetooth Low Energy (BLE), which has become important for developing wearable and portable medical devices due to its low energy consumption and robust connectivity options.

Sensor Solutions

Medical practitioners require the measurement of many biometrics. Effective sensors applied to the patient are required to measure vital signs (heart rate, blood pressure, temperature, respiration rate, pO2) or detailed data such as ECG. Sensors must be comfortably worn, easy to apply, and provide verifiably accurate data throughout the intended use period.

  • Vital Signs sensors use mechanical, electrical, thermal, or optical means to monitor dynamic body functions that are traditionally measured manually and intermittently – heart rate, respiration rate, blood pressure, and temperature.
  • Blood characteristics such as glucose and oxygen levels can be measured transdermally, reducing the need for finger sticks and blood draws. Sensors can also perform diagnostics based on perspiration chemistry.
  • Some implants have active components that need to communicate with other system components. In this case, a radio “sensor” may need to be worn to receive the data the implant is transmitting.
  • Health outcomes depend on activity levels, which can be monitored with accelerometers and GPS sensors. Physical therapy and exercise can be monitored with sensors that measure angles, distances, and forces.

Battery-Powered Systems

Battery-operated point-of-care (POC) devices that reduce delays and cost of lab work by bringing the test to the patient are becoming more predominant. DeviceLab has successfully designed many battery-powered devices. We are well versed in all the latest battery technologies, even in with rapidly evolving technologies. Our designs have maximized battery efficiency to achieve impressive and predictable run times.

DeviceLab is experienced in the design of wired and wireless chargers that preserve battery life and recharge rapidly to minimize device downtime for your medical device regardless of the size and form of the wireless medical device.

Wearable Wireless Medical Devices

DeviceLab has a proven successful track record designing devices adhered to, worn on, or applied to various parts of the body, for patients of all types. Many additional regulations apply to wearable devices, including human factors of use, patient contact materials, and limits on the delivery of energy to the body (active medical devices). Wearable devices present other unique challenges, such as:

  • Accommodating a wide variety of anatomy differences while maintaining required accuracy.
  • Electronic miniaturization and tight packaging
  • Excellent ingress protection from dirt, liquids, and other compounds.
  • Durability from the environment and outdoor exposure.
  • Immunity to altitude changes and electromagnetic interference.

DeviceLab has the experience and expertise in digital health to develop reliable wearable wireless medical devices that overcome these challenges and meet higher standards.


Wireless Communications for Medical Devices

Wireless connectivity technology is needed for digital health but is especially suited to wearable devices, allowing for data to be easily transferred between small sensors and smartphones and other clients on cellular or local area networks.

  • Zigbee (IEEE 802.15)
  • Near Field Communications (ISO/IEC 18092 / 21481)
  • Body Area Network (IEEE 802.15.6)

We have the wireless hardware expertise required to implement these protocols. Our implementations of wireless links are fault-tolerant, reliable, and exploit the full bandwidth of the protocol. The devices we develop readily connect, stay connected, and reconnect easily after interruptions of service.

Application Software for Digital Health

Users participate in digital health mostly through application software. Running on consumer devices like iPhones or custom-built medical devices, software provides data display, archiving, interpretation, and manages the communications that are key to digital health. Medical apps, unlike general software applications on consumer devices, must be completely secure, fault-tolerant, and error-free to preserve patient privacy and preclude medical errors. Some digital healthcare products are software only (e.g. an app on an Apple Watch), but are still regulated by the FDA, requiring expertise the average software developer does not possess. DeviceLab’s team of Engineers have the skills and experience to create compliant software and regulatory documentation to ensure a smooth submission process.

Cloud Software and Connectivity for Digital Health

It is now possible to connect multiple sites and devices for the sharing of medical data with the advent of secure and reliable cloud services. Cloud services include online access, visualization of data, and data processing in the cloud. The benefits derived include the security of a distributed, broadly accessible databank and the ability to perform sophisticated analyses of very large datasets. DeviceLab has the know-how to deliver software solutions that securely connect your system to a cloud server to offer extended services, including remote diagnostics, data collection for analytics, and patient/practitioner data sharing.

Many applications require data exchange with an existing Hospital Data System and interoperability with a variety of connected instruments. DeviceLab has years of experience with these systems with several successfully deployed devices.
