Nordic-powered wearable enables continuous ECG

Jan 19, 2026

Dandelion Medical Devices, Inc. (DMD) in partnership with global engineering services company Cloud2GND, has developed a compact, disposable, wearable electrocardiogram (ECG) monitoring device for non-critical care settings. ‘PulseTape ECG™’ is a wireless Holter-style wearable designed to continuously record single-channel ECG data over extended monitoring periods within routine clinical workflows.

Using the Bluetooth® LE wireless connectivity provided by Nordic Semiconductor’s nRF52840 SoC, sensitive medical data is securely relayed from the wearable to a smartphone, tablet, or clinical workstation for clinician review. The device is supported by a patient-facing smartphone app that enables device activation, secure data upload, and automated report routing to clinicians.

PulseTape ECG incorporates a microsensor suite, including a single-lead ECG sensor coupled with wet electrodes, as its primary modality for long-term rhythm monitoring. The device is designed to be fully disposable and patient-applied, eliminating the need for device return or reuse and reducing the logistical and compliance burdens associated with traditional ambulatory ECG monitors.

In addition to providing low power wireless connectivity for secure pairing and data transfer, the nRF52840 SoC’s 64 MHz, Arm® Cortex® M4 processor with floating point unit (FPU) supervises the integrated sensors and executes device firmware developed by Cloud2GND using Nordic’s nRF Connect SDK (Software Development Kit) and the Zephyr RTOS. The firmware supports efficient sensor management, data handling, and power-optimized device operation.

PulseTape ECG represents DMD’s first product built on the company’s broader PulseTape™ Platform, which is designed to capture, transmit, and contextualize cardiovascular data across multiple care settings. The platform incorporates a multi-sensor architecture with secure Nordic SoC-powered Bluetooth LE connectivity and cloud integration, supporting future expansion into additional monitoring applications.

Each PulseTape ECG is designed to operate for up to two weeks on compact button-cell batteries under typical connection intervals, according to the company.

We work with clients from concept and requirements definition through working prototypes, validation, and manufacturing preparation.
