What is 3D-MID? Molded parts with integrated electronics from HARTING
3D-MID (three-dimensional mechatronic integrated devices) tech combines electronic and mechanical functionalities into a single, 3D component. It replaces the traditional printed circuit board and opens up many new opportunities. It takes injection-molded parts and uses laser-direct structuring to etch areas of conductor structures, which are filled with a copper plating process to create very precise electronic circuits. HARTING, the technology's developer, says it's "Like a PCB, but 3D." Tons of possibilities.

The next big thing? Researchers develop ultra-fast charging batteries that last 20 years
Scientists at Nanyang Technology University (NTU) in Singapore have developed ultra-fast charging batteries that can be recharged up to 70 percent in only two minutes. The new-generation batteries also have a long lifespan of over 20 years -- more than 10 times compared to existing lithium-ion batteries.
This breakthrough has a wide-ranging impact on all industries, especially for electric vehicles, where consumers are put off by the long recharge times and limited battery life.
(Clockwise from top) NTU Assoc. Prof. Chen Xiaodong with research fellow Tang Yuxin and PhD student Deng Jiyang.
With this new technology, drivers of electric vehicles could save tens of thousands on battery replacement costs and can recharge their cars in just a matter of minutes.
Commonly used in mobile phones, tablets, and in electric vehicles, rechargeable lithium-ion batteries usually last about 500 recharge cycles. This is equivalent to two to three years of typical use, with each cycle taking about two hours for the battery to be fully charged.
In the new NTU-developed battery, the traditional graphite used for the anode (negative pole) in lithium-ion batteries is replaced with a new gel material made from titanium dioxide.
Titanium dioxide is an abundant, cheap, and safe material found in soil. It is commonly used as a food additive or in sunscreen lotions to absorb harmful ultraviolet rays.
Naturally found in spherical shape, the NTU team has devised a way to transform the titanium dioxide into tiny nanotubes, which are a thousand times thinner than the diameter of a human hair. This speeds up the chemical reactions taking place in the new battery, allowing for superfast charging.
Invented by Associate Professor Chen Xiaodong from NTU's School of Materials Science and Engineering, the science behind the formation of the new titanium dioxide gel was published in the latest issue of Advanced Materials, a leading international scientific journal in materials science.
Prof. Chen and his team will be applying for a proof-of-concept grant to build a large-scale battery prototype. With the help of NTUitive, a wholly-owned subsidiary of NTU set up to support NTU start-ups, the patented technology has already attracted interest from industry.
The technology is currently being licensed by a company for eventual production. Prof. Chen expects that the new generation of fast-charging batteries will hit the market in the next two years. It also has the potential to be a key solution in overcoming long-standing power issues related to electro-mobility.
"Electric cars will be able to increase their range dramatically, with just five minutes of charging, which is on par with the time needed to pump petrol for current cars," said Prof. Chen. "Equally important, we can now drastically cut down the toxic waste generated by disposed batteries, since our batteries last 10 times longer than the current generation of lithium-ion batteries."
The 10,000-cycle life of the new battery also means that drivers of electric vehicles would save on the cost of battery replacements, which could cost over US $5,000 each.
Easy to manufacture
Lithium-ion batteries usually use additives to bind the electrodes to the anode, which affects the speed in which electrons and ions can transfer in and out of the batteries.
However, Prof. Chen's new cross-linked titanium dioxide nanotube-based electrodes eliminate the need for these additives and can pack more energy into the same amount of space.
Manufacturing this new nanotube gel is very easy. Titanium dioxide and sodium hydroxide are mixed together and stirred under a certain temperature, so battery manufacturers will find it easy to integrate the new gel into their current production processes.
Recognized as the next big thing by co-inventor of today's lithium-ion batteries
NTU professor Rachid Yazami, the co-inventor of the lithium-graphite anode 30 years ago that is used in today's lithium-ion batteries, said Prof. Chen's invention is the next big leap in battery technology.
"While the cost of lithium-ion batteries has been significantly reduced and performance has improved since Sony commercialized it in 1991, the market is fast expanding towards new applications in electric mobility and energy storage," said Prof. Yazami, who is not involved in Prof. Chen's research project.
Last year, Prof. Yazami was awarded the prestigious Draper Prize by The National Academy of Engineering for his ground-breaking work in developing the lithium-ion battery with three other scientists.
"However, there is still room for improvement, and one such key area is the power density -- how much power can be stored in a certain amount of space -- which directly relates to the fast-charge ability," Prof. Yazami said. "Ideally, the charge time for batteries in electric vehicles should be less than 15 minutes, which Prof. Chen's nanostructured anode has proven to do so."
Prof. Yazami is now developing new types of batteries for electric vehicle applications at the Energy Research Institute at NTU.
This battery research project took the team of four scientists three years to complete. It is funded by the National Research Foundation (NRF), Prime Minister's Office, Singapore, under its Campus for Research Excellence and Technological Enterprise (CREATE) Program of Nanomaterials for Energy and Water Management.
