Samsung: Fitness tracker in the form of a patch

2021: Device Announcement

In early June 2021, Samsung introduced a fitness tracker in the form of a patch with an OLED display. The device monitors and outputs information about biometric processes.

As part of the project, specialists from the Samsung Advanced Institute of Technology (SAIT) center managed to achieve stable indicators of a stretchable device with a high elongation coefficient. They were able to combine a stretchable organic LED display and a photoplethysmography (PPG) sensor in one device with a "stretchable electronic skin" form factor that measures and displays the user's heart rate in real time. The sensors and display of the device continue to work and their performance does not deteriorate even when stretched to 30%.

The technology allows you to measure biometric data for a long time without having to remove the device when you sleep or exercise - the patch feels like part of your skin. You can also check your data directly on the screen without transmitting it to an external device, "said Junjun Yun, doctor of technical sciences at SAIT.

In addition, as stated in Samsung, for the first time in the industry, the commercial potential of stretching gadgets was demonstrated, especially in combination with a number of existing semiconductor processes. The success of this example proves the possibility of other ways of applying the technology. Thanks to the study, stretching devices are expected to become even more widespread in the future, the South Korean manufacturer said in a statement.

By June 8, 2021, Samsung did not announce the timing of the commercial launch of the technology. The company only noted that soon it can be used to support health monitoring systems, especially in wearable medical products.^[1]
