Disposable health patch is mostly printed, ultra-low cost: Page 2 of 2

January 08, 2019 // By Julien Happich
At the Consumer Electronics Show, imec and TNO have unveiled the latest version of their health patch. Developed in the framework of the Holst Centre in Eindhoven, the new health patch can be worn for up to seven days before needing to be replaced, manufactured from flexible materials at a fraction of the cost of previous generations.

For patients, a single, disposable patch that can be worn for several days is more convenient and can reduce hospital visits as it no longer needs to be returned after use. This is particularly important for chronically ill patients as it provides an affordable, single-use device that can be easily used to monitor their vital signs and physical activity at home. Easy to apply and comfortable to wear for long periods of time, it enables patients to perform their normal daily activities with minimal impact while providing valuable information to optimize their treatment and medication. The single-use concept can also reduce time spent in the hospital as it allows patients to be sent home earlier while still remotely monitoring their vital signs.

The new patch now also measures blood oxygen saturation (SpO2). This is an important vital sign for assessing a patient’s physical health as low blood oxygen levels can indicate hypoxemia which – if untreated – can compromise organ functions and can even lead to respiratory or cardiac arrest. It also includes an accelerometer for tracking physical activity, an ECG heart activity tracker and bioelectrical impedance monitoring.
“Traditionally, blood oxygen saturation is measured with a separate device attached to the finger. This is not very practical for daily living, so we developed a new technique that performs the measurement with a chest patch, via reflective photoplethysmography. By adding this sensing capability to our wearable solution, we are now able to measure three essential vital signs - heart rate, breathing rate and blood oxygen saturation - with a single unobtrusive and comfortable chest patch,” Grundlehner said.
