True-meaning wearable displays: Self powered, washable and wearable
When we think about clothes, they are usually formed with textiles and have to be both wearable and washable for daily use; however, smart clothing has had a problem with its power sources and moisture permeability, which causes the devices to malfunction. This problem has now been overcome by a research team, who developed a textile-based wearable display module technology that is washable and does not require an external power source.
Stretchable multi-functional fibre
Fiber-based electronics are expected to play a vital role in next-generation wearable electronics. Woven into textiles, they can provide higher durability, comfort, and integrated multi-functionality. A research team has developed a stretchable multi-functional fiber that can harvest energy and detect strain, which can be applied to future wearable electronics.
E-textiles at CES 2019
Once again, CES 2019 displayed many examples of e-textile products throughout the exhibition floor. As ever, companies ranged from early stage start-ups scattered throughout "Eureka Park", through to some of the best known and longest established players with booths (generally in the Sands Expo). In this article, we will describe our overall impressions, followed by listing summaries of each of the companies that we visited and interviewed.
A novel material for transparent and flexible displays
The next generation of flexible and transparent displays will require a high-performing and flexible polymeric material that has the optical and thermal properties of glass. The material must be transparent to visible light and have a low coefficient of thermal expansion. Unfortunately, such a polymeric material has not been available.
KAIST OBELAB showed its research on a brain imaging system NIRSIT at CES 2019
IDTechEx met with Hamin Shin from KAIST. Hamin works within the ADVNANO (Advanced Nano - Energy and Materials) lab under Professor Il-Doo Kim. They demonstrated a poster showing the process that they had developed for coating yarns. The yarn is treated with jetted metal via an electrospinning process.
Shape-conformable batteries based on 3D-printing technology
Flexible, wireless electronic devices are rapidly emerging and have reached the level of commercialization; nevertheless, most of battery shapes are limited to either spherical and/or rectangular structures, which results in inefficient space use.
Silk adhesive paves the way for epidermal electronics
Producing effective epidermal electronics requires a strong, biocompatible interface between a biological surface and a sensor. A research team has employed a calcium-modified silk fibroin as a biocompatible and strong adhesive. This technology led to the development of epidermal electronics with strong adhesion for patients who need drug injections and physiological monitoring over a long time.
Flexible transparent force touch sensor
Researchers reported a high-performance and transparent nanoforce touch sensor by developing a thin, flexible, and transparent hierarchical nanocomposite film. The research team says their sensor simultaneously features all the necessary characters for industrial-grade application: high sensitivity, transparency, bending insensitivity, and manufacturability.
Spray coated tactile sensor on a 3D surface for robotic skin
Robots will be able to conduct a wide variety of tasks as well as humans if they can be given tactile sensing capabilities. A research team has reported a stretchable pressure insensitive strain sensor by using an all solution-based process.
Improved efficiency of CQD solar cells using an organic thin film
Recently, the power conversion efficiency of colloidal quantum dot -based solar cells has been enhanced, paving the way for their commercialization in various fields; nevertheless, they are still a long way from being commercialized due to their efficiency not matching their stability.
Flexible drug delivery microdevice to advance precision medicine
A research team has developed a flexible drug delivery device with controlled release for personalized medicine, blazing the path toward theragnosis.
LG expands investments in robot innovators
LG Electronics' recent investment in US-based Bossa Nova Robotics marks the first overseas investment in a robotics partner by LG following a number of deals with Korean startups over the past year. In total, LG has committed over USD 90 million to robotics startups in the first 12 months of its investment initiative.
