Apple new generation iphones- What to expect?

                 Hold on to your nerves till September  9(likely) if you are planning for an   iPhone purchase. Apple is soon likely to announce the launch of its new generation iPhones. If rumors are to be believed the company is planning to hold a big event early in September to take the wraps of its next iPhone, According to sources the event will happen on September 9^th as all their iPhones have been introduced in the time frame ever  since 2011.

  

Iphone 6s/6sPlus or Iphone 7

   It is expected that Apple will stick to its naming scheme calling the new versions iPhone 6 or 6plus, but it might also call it “I Phone 7” due to its significant internal improvements rather than an updated external look

Expected Features    

• The new iphones won't be a fat phone, We can  expect roughly the same dimensions as that of the current ones. It looks certain that it can probably a 4.7 inch phone. It's expected that Apple will continue its trend, offering the new  iPhone in two separate sizes

•  It would feature a dual lens setup that will help the iphone capture more lights with optical zoom camera capability in place of digital lens. The dual lens will be equipped to capture DSLR images

• Force touch technology similar to that of apple watches to distinguish between light tap and deep press.

• Higher screen resolution is also a possibility

•  The rumoured features also includes A9 processor and 2GB RAM

• Apple is also planning to upgrade the minimum storage capacity option to 32gb

          In addition to the iphones , Apple is also expected to unveil the next generation apple tv alongside an Internet-delivered television service. The Apple TV will be featuring an updated A8 processor, a full App Store, a touch-based remote control. With new releases apple is trying to regain its position in the market

Wearable Tech can be made using Inkjet printers

Researchers have found a new way to use inkjet printing technology to produce electronic circuits made of liquid metal alloys for soft robots and flexible electronics. However, new manufacturing techniques must be developed before soft machines become commercially feasible, said Rebecca Kramer, an assistant professor of mechanical engineering at Purdue University. 

"We want to create stretchable electronics that might be compatible with soft machines, such as robots that need to squeeze through small spaces, or wearable technologies that aren't restrictive of motion," she said. 

A new manufacturing approach focuses on using inkjet printing to create devices made of liquid alloys. "This process now allows us to print flexible and stretchable conductors onto anything, including elastic materials and fabrics," Kramer said.

WORKING

 Ultrasound is used to make the printable ink by dispersing the liquid metal in a non-metallic solvent, the ultrasound breaks up the bulk liquid metal into nanoparticles and this nanoparticle-filled ink is compatible with inkjet printing. 

"Liquid metal in its native form is not inkjetable," Kramer said. "So what we do is create liquid metal nanoparticles that are small enough to pass through an inkjet nozzle. Sonicating liquid metal in a carrier solvent, such as ethanol, both creates the nanoparticles and disperses them in the solvent. Then we can print the ink onto any substrate. The ethanol evaporates away so we are just left with liquid metal nanoparticles on a surface." 

The nanoparticles must be rejoined after printing and this is achieved by applying light pressure, which renders the material conductive. This step is necessary because the liquid metal nanoparticles are initially coated with oxidised gallium, which acts as a skin that prevents electrical conductivity. 

"But it's fragile, so when you apply pressure it breaks the skin and everything coalesces into one uniform film," Kramer said. "We can do this either by stamping or by dragging something across the surface, such as the sharp edge of a silicon tip" she added.

The process could make it possible to rapidly mass-produce large quantities of the film. Future research will explore how the interaction between the ink and the surface being printed on might be instrumental in the production of specific types of devices. 

"For example, how do the nanoparticles orient themselves on hydrophobic versus hydrophilic surfaces? How can we formulate the ink and exploit its interaction with a surface to enable self-assembly of the particles?" Kramer said. 

The researchers will also study and model how individual particles rupture when pressure is applied, providing information that could allow the manufacture of ultrathin traces and new types of sensors.
