First 3D Food Printing Technology in Asia

Hong Kong Technology Startup, Alt Farm announced the debut of the first-ever 3D food printing technology for high-quality and creative food in Asia that achieves a level of product quality comparable to high-quality plant-based food, resulting in a far more efficient, sustainable, and ethical way to create foods without compromising on quality.

Anti-Bacterial Graphene Face Masks

Face masks have become an important tool in fighting against the COVID-19 pandemic. However, improper use or disposal of masks may lead to "secondary transmission". A research team has successfully produced graphene masks with an anti-bacterial efficiency of 80%, which can be enhanced to almost 100% with exposure to sunlight for around 10 minutes.

New Cathode Coating Extends Lithium Ion Battery Life

The new coating, called PEDOT, marks a breakthrough in lithium-ion battery technology since it fully and completely protects each particle of the cathode — inside and out — from reactivity with the electrolyte.

Bionic Eye that Works Like the Real One

A research team has developed an artificial visual system that uses a spherical biomimetic electrochemical eye with hemispherical retina made of a high-density perovskite nanowire array.

Alibaba unveils its own AI chip

Alibaba Group plans to launch its first self-developed AI inference chip, which has potential for use in autonomous driving, smart cities and smart logistics. In addition to this, the Academy will boost its R&D in AI chips for training on the cloud and for IOT applications.

Graphene Frontiers awarded grant for roll-to-roll graphene production

Graphene Frontiers, a company developed through the University of Pennsylvania's Center for Technology Transfer, has been awarded a $744,600 grant from the National Science Foundation to develop roll-to-roll production of graphene, the "miracle material" at the heart of the 2010 Nobel Prize in Physics.

Graphene provides efficient electronics cooling

A layer of graphene can reduce the working temperature in hotspots inside a processor by up to 25 percent - which can significantly extend the working life of computers and other electronics.

Early printed electronics revisited

There was an element of back to the future at the hugely successful recent Printed Electronics Europe event in Dresden. Although a high proportion of printed electronics has progressed from screen printing to other printing technologies, notably inkjet, for better control, less waste of these expensive inks and other benefits, at least one company has reverted to advanced rotary screen printing to gain throughput. Indeed, Professor Edgar Dörsam reported that his team has achieved feature size of better than one micron with its advanced screen printing methods. Daetwyler even announced a capability of gravure printing below five microns in feature size with its machines.

Less than one week to Printed Electronics Europe 2010

Next week the sixth annual IDTechEx Printed Electronics Europe event takes place in Dresden, Germany on April 13-14. Read about some of the event highlights here.

Race for color video e-readers

The e-reader is a killer application involving printed electronics. Despite costing more than an i-Pod, the Amazon Kindle achieved 500,000 unit sales in its first year of trading last year and now we are talking of millions. The i-Pod, an iconic success, only achieved 300,000 unit sales in its first year of trading.

Flexible printed LCDs part two

Bistable flexible LCDs may be an advance on flexible electrophoretic displays for e-books, e-labels and other applications.

Flexible printed LCDs part one

Several companies have now made experimental samples of flexible LCD displays and, although most have serious limitations as yet, they may provide a way forward.

Printed and thin film electronics in Hong Kong

Dr Peter Harrop, IDTechEx meets a few of the people working on printed electronics and allied matters at the historic University of Hong Kong.
