BLE- and Bluetooth-Based Wristband Delivers Personalized Health Information

Maxim Integrated has released its HSP 2.0 wristband system—which measures temperature levels, as well as respiratory and heart health, via IoT data—that companies can use to create solutions for individuals wanting control of their own health-care data.

As part of the growing trend toward consumer wearable devices, Maxim Integrated has developed a health-care-based wristband system using Internet of Things (IoT) technology, known as Health Sensor Platform (HSP) 2.0. The solution is intended to put the management of one's own health and wellbeing more firmly in the hands of a person wearing the device. The watchband consists of multiple sensors, including an electrocardiogram (ECG) sensor and photoplethysmogram (PPG) sensors to measure heart rate and variation, as well as a Bluetooth or Bluetooth Low Energy (BLE) connection to a mobile phone or device. It comes with an IoT app enabling users to receive and manage the sensor-based data.

Maxim Integrated, an IC and sensor technology company, has been developing clinical-grade sensor products to fulfil the needs of a market in which individuals sought greater ownership of their health data, says Andrew Burt, the firm's executive business manager. He cites such products as watches, cardiac patches and diabetic patches that capture measurements, which can inform users and their physicians regarding their health throughout the day.

Maxim Integrated's HSP 2.0 wristband
While wristband sensors for monitoring health are already available on the market, Maxim Integrated reports, the HSP 2.0 is unique in that it offers sensor-based data about ECG readings and PPG heart rate signals. It also comes with an open platform so users can develop their own software-based solution in which data can be stored and evaluated, without requiring a technology provider (such as Apple or FitBit) to manage that data.

An ECG sensor measures the electrical activity of each heartbeat and detects the wave that causes the muscles to squeeze, thereby pumping blood from the heart. Tracking this activity within the heart can help patients to better understand their cardiac health, but most sensors that can monitor ECG readings must be applied directly to a person's chest. Maxim's engineers have developed a sensor that can detect ECG data directly from the wrist's own pulse.

The ability for customers to manage this data themselves makes the platform appealing, Burt says, noting that several developmental steps led to the HSP 2.0's release. Approximately two years ago, Maxim Integrated released a developer's kit that enabled users to create their own reference designs for wearable sensors. This summer, the firm released a health band incorporating an ECG sensor. The most recent development was the open software platform, linked to the new wristband, which allows users to take the raw data made available by the system, and tailor their solution according to the information they want to collect and analyze.
