Samsung is testing stretchable displays with heartbeat sensor

Consumer electronics maker Samsung has launched numerous displays over the years, including vibrant flexible displays in some of its premium devices. According to Samsung, the researchers were able to integrate a stretchable organic LED display along with a photoplethysmography sensor in a single device to measure as well as display a user’s heart rate in real-time. The team tested their work by attaching the stretchable PPG heart rate sensor and OLED display system to the inner wrist near the radial artery. To address this issue, the researchers replaced the plastic material used in existing stretchable displays with elastomer – an advanced material with high elasticity and resilience, and further strengthened the material’s heat resistance, Samsung noted. “We plan to incorporate stretchable sensors and high-resolution freeform displays to enable users to monitor things like peripheral oxygen saturation, electromyogram readings and blood pressure.”
