A design for a beautiful colostomy bag

“Inspired by my family’s own struggle with Crohn’s Disease, this appliance empowers people to feel more confident with their body and provides some freedom from an ostomy pouch,” designer Stephanie Monty explains

The flexible device adheres to the wearer’s skin, and is covered with a waterproof membrane that creates a “natural, skin-like feel”. The silicone can also be color-matched to the user’s skin.

has any one fictional character ever had quite as much wasted potential as ontari kom azgeda holy shit 

like dudes they didnt even just waste her potential they fucking dragged it through the mud. aesthetically she was such? a powerhouse in her first ep? god. stolen at birth and raised by THE ICE QUEEN like ok ok ok what kinda,,,, epic tragic backstory ok alright. and she had the potential to be so strong and complex like i took one look at her and i was sold i figured she’d win me over in a heartbeat. she had so much going for her and then what did she turn into? 

literally just a flexible plot device. first she was a nice segway into a soft science explanation of lexa’s nightblood. then she was The Big Bad Guy who killed the nightbloods and wanted to take control of the coalition (for no god damn reason that they bothered to develop for her). then she was literally a rapist (for no god damn reason!!!) which got swept under the rug by the time they needed to use her as a gullible idiot who lets alie and the chipmunks take over polis. then she was a bloodbag?? honestly ive never been more disappointed with the use of a character. she had So Much Potential. what in the fuck-

Research leads to a golden discovery for wearable technology

Some day, your smartphone might completely conform to your wrist, and when it does, it might be covered in pure gold, thanks to researchers at Missouri University of Science and Technology.

Writing in the March 17 issue of the journal Science, the Missouri S&T researchers say they have developed a way to “grow” thin layers of gold on single crystal wafers of silicon, remove the gold foils, and use them as substrates on which to grow other electronic materials.

Liquid metal ‘balloons’ offer room-temperature soldering
Invention could help the microelectronics industry to connect circuit-board components without risking heat damage.

Put away that hot iron, and stow the solder: you can now forge a connection between two bits of metal at room temperature.

Soldering is a mainstay of the microelectronics industry, which uses hot molten metal to connect components on printed circuit boards. But conventional hot soldering techniques can sometimes damage the materials used in flexible electronic devices, or the ever-smaller parts on today’s microchips.

Martin Thuo at Iowa State University in Ames has now developed a clever way of soldering that requires no heat, using an alloy of bismuth, indium and tin called Field’s metal. At room temperature, this mixture is normally a solid — it melts at 62 °C. But if tiny droplets of the molten metal are encapsulated in a protective shell, they remain liquid when the shell cools and solidifies.

This effect, known as undercooling or supercooling, arises because the liquid metal is prevented from coming into contact with anything that triggers solidification — a speck of dust, say. The effect has been widely studied, but until now there was no way to make stable undercooled metal particles in a readily usable form. “They’re almost like water balloons of liquid metal,” explains Michael Dickey, a materials scientist at North Carolina State University in Raleigh.

Crushing the particles releases the liquid metal, which quickly solidifies to form a neat, conductive solder joint. “I haven’t seen this before, I think it’s quite unique,” says Johan Liu, a materials scientist at Chalmers University of Technology in Gothenburg, Sweden, who develops techniques for electronics manufacturing.

Tattoo-like 'e-skin' turns your body into digital screen

In a yet another example to integrate electronic devices with the human body, researchers from the University of Tokyo have developed an ultrathin, protective layer that will help create “electronic skin” displays of blood oxygen level, e-skin heart rate sensors for athletes and other applications.

The team demonstrated its use by creating an air-stable, organic light-emitting diode (OLED) display.

Integrating electronic devices with the human body to enhance or restore body function for biomedical applications is the goal of researchers around the world.

Wearable electronics, in particular, need to be thin and flexible to minimise impact where they attach to the body.

However, most devices developed so far have required millimetre-scale thickness glass or plastic substrates with limited flexibility, while micrometer-scale thin flexible organic devices have not been stable enough to survive in air.

Will Electronic Contact Lenses Monitor Your Health?

by Charles Q. Choi

Thin, transparent electronic devices small and flexible enough to wrap around a human hair could help lead to smart contact lenses and many other applications on or in the body, researchers say. 

Scientists would like the breakthroughs made in electronics over the past century to go into new devices that could improve human health. That’s why research teams around the world are now working on extremely thin electronics that, unlike conventional microchips, are bendable and compatible with the flexible nature of the human body.

Electrical engineer Giovanni Salvatore and his colleagues at the Swiss Federal Institute of Technology in Zurich have developed a simple method for transferring such electronics onto nearly any surface.

Laser And Plastic Sheets Make Cheap, Powerful Energy Storage Device

by Michael Keller

It was just a month ago when we reported researchers had discovered they could cheaply make graphene by firing a laser at common plastic.

The Rice University scientists who took the innovative approach to easily make the supermaterial have been hard at work ever since. They say they have already had success turning their laser-induced graphene into advanced energy storage devices.

Chemists in the lab of James Tour fired their laser at both sides of a polyimide plastic sheet to create layers of graphene flakes sandwiching the polymer. They then stacked the graphene and plastic sheets on top of each other to create three-dimensional supercapacitors, power storage devices that charge and discharge electric current much faster than batteries but can hold less energy.

  • Carlos: Cecil! I made a highly complex invention, that will change the human lifestyle forever! Ok so, you know how when you wake up earlier in the morning because of the sun blaring your eyes through the window? Well I've made a device that hangs, in front of your window, and BLOCKS out the sunlight from entering your room!
  • Cecil: .....Cur...tains?
  • Carlos: N-No no, this device is flexible so you can open and close it if you decide to let the light in-
  • Cecil: CuRRRRtains?
  • Carlos: Cecil, please. I've been making this for 2 weeks without any sleep. Just let me have this.
Device Harvests Energy From Moving Organs To Power Implants

by Michael Keller

Your heart expends half a joule of energy every time it beats. That’s the same amount of juice you’d need to lift an apple 1.6 feet off the ground.

Before every contraction, the potential energy trapped in chemical bonds within cardiac muscle cells is released and converted into the mechanical power of the heartbeat. But, like all energy, that which is harnessed to power the heart is never destroyed; it just changes form as it radiates away from the organ as heat and vibrations of surrounding tissue and fluid. 

Now, a science team has announced a breakthrough in harvesting the energy released from the movement of the beating heart, the breathing lung and the flexing diaphragm. They’ve developed a superthin device that can be attached to an organ to generate electricity from its movements.
