Scalable electronic technology is an emerging field that gives electronic parts the flexibility to be as rubber-like. In recent years, innovative research into the application of this technology to sensors has grown.
Scalable electronic technology is an emerging field that gives electronic parts the flexibility to be as rubber-like. In recent years, innovative research into the application of this technology to sensors has grown. Frost & Sullivan conducted a survey on this topic.
Technological innovation in academia and industry
1. New Zealand industry: The industry has developed soft sensors made of cloth and silicone to measure complex movements of people or objects, such as stretching, extrusion and bending. It is also planned to add a power generation device to allow the sensor to be charged via human motion. The use of such sensors does not cause discomfort to the human body and provides accurate information on motion.
2. University of Manitoba, Canada: The research team combines chewing gum with carbon nanotubes to make retractable sensors, chewing gum is used as a stretchable material, and carbon nanotubes are used for sensing. This sensor accurately detects slow motion and breathing, as well as changes in humidity. This technology has the opportunity to be used in wearable devices and healthcare.
3. Korea Academy of Science and Technology: Researchers use silver nanowires to make retractable electrodes and use them to make small, flexible generators. The invention can be used in wearable and biomedical applications to allow the device to self-charge, such as e-skin or flexible displays.
Technical roadmap
The 2016 technology development focuses on health tracking bracelets, smart watches and patient monitoring devices.
By 2017, smart devices such as flexible screens and flexible mobile phones have become the mainstream of research and development.
In 2018, sensors will be put into practical use in the industry.
In 2019, smart sensors for IoT devices, motion sensors, sensors that detect biological messages (such as heartbeat frequency), and technologies that collect information via sensor fusion will grow.
The 2020 technology spindle is the development of smart glasses and augmented reality glasses, which led to the manufacture of military head-up displays.

Outlook for 2020
1. With the assistance of the Flexible Hybrid Electronic InsTItute, the United States Department of Defense (DoD) received $75 million in the field of scalable sensors for more than five years. Funding, and a total of $90 million in funding from industry, academia and local governments. Scalable sensors will have long-term effects on military applications such as IoT wearable health monitors or building health monitoring.
2. Flexible solar cells will bring a wide range of applications, such as integration with wristbands as energy capture devices.
3. In the long run, the US market is expected to see significant growth with the mass production of scalable sensors in the fields of Internet of Things, consumer electronics, military and medical.
