Ultrathin, elastic skin display
.
Why is it in news?
Japanese researchers develop ultrathin, highly elastic skin display
Details
- The device displays electrocardiogram recorded by skin sensor, holds promise for home healthcare applications.
- Thanks to advances in semiconductor technology, wearable devices can now monitor a person’s health by first measuring vital signs or taking an electrocardiogram, and then transmitting the data wirelessly to a smartphone.
- The readings or electrocardiogram waveforms can be displayed on the screen in real time, or sent to either the cloud or a memory device where the information is stored.
- Combined with a wireless communication module, this integrated biomedical sensor system, called “skin electronics”, can transmit biometric data to a cloud. This product is the result of research by a Japanese academic-industrial collaboration, led by Professor Takao Someya at the University of Tokyo’s Graduate School of Engineering.
- The newly-developed skin electronics system aims to go a step further by enhancing information accessibility for people such as the elderly or the infirm, who tend to have difficulty operating and obtaining data from existing devices and interfaces.
- It promises to help ease the strain on home health-care systems in ageing societies through continuous, non-invasive health monitoring and self-care at home. The new integrated system combines a flexible, deformable display with a lightweight sensor composed of a breathable nanomesh electrode and wireless communication module.
- Medical data measured by the sensor, such as an electrocardiogram, can either be sent wirelessly to a smartphone for viewing or to the cloud for storage. The skin displayconsists of a 16x24 array of micro LEDs and stretchable wiring mounted on a rubber sheet. The sensor can be worn on the skin continuously for a week without causing any inflammation.
- Although this sensor, developed in an earlier study, was capable of measuring temperature, pressure and myoelectricity (the electrical properties of muscle), it successfully recorded an electrocardiogram for the first time in the latest research.
