Temporary Tattoo Instead Of Finger Prick For Diabetics

Temporary Tattoo Instead Of Finger Prick For Diabetics

Diabetics may not have to prick their fingers with a needle to monitor their glucose levels in the near future. Researchers at the University of California, San Diego have discovered a way to test and monitor glucose levels by using a small, stick-on temporary tattoo.

Globally, diabetes is one of the leading causes of death. According to the Centers for Disease Control and Prevention (CDC), close to 29.1 million people in the United States have diabetes. Moreover, 1 out of 4 people do not know they have the disease. This is why the recent scientific advancement and discovery will be a most welcome change for existing and future diabetics.

Currently, diabetics manage this most unfortunate condition by painfully getting blood samples from their fingers. Diabetics use the traditional method of monitoring their glucose levels to prevent problems associated with diabetes by sticking their fingers with a small needle multiple times throughout the day.

Diabetics Welcome This New Discovery

Recently, a University of California, San Diego graduate student named Amay Bandodkar created an electronic device, which has the potential of replacing the traditional methods of monitoring glucose levels in diabetics. This innovative device is made up of an electronic sensor, with interwoven electrodes printed on tattoo paper.

The way it works is quite extraordinary. Diabetics can simply place the temporary tattoo on their arm and the device measures the patient’s glucose levels continuously throughout the day.

Creator Amay Bandodkar provided EurekAlert more information about his new invention.

“The readout instrument will also eventually have Bluetooth capabilities to send this information directly to the patient’s doctor in real-time or store data in the cloud.”

He added, “Presently the tattoo sensor can easily survive for a day. These are extremely inexpensive, a few cents, and hence can be replaced without much financial burden on the patient.”

Bandodkar and a team of nanoengineers at the university developed and tested this amazing device in Professor Joseph Wang’s laboratory at the NanoEngineering Department and the Center for Wearable Sensors at the Jacobs School of Engineering at UC San Diego. The team was able to provide documented evidence that the electronic sensor will function as intended and work at measuring glucose levels.

Researchers at the university performed an early trial on seven men and women between the ages of 20 and 40. The participants were not diabetics; however, the test results revealed the temporary tattoo was just as accurate as a finger-prick test. Additionally, the volunteers reported they hardly felt anything while wearing the device; they only felt a mild tingling sensation for about 10 seconds.

How The Tattoo Works At Managing Diabetes

The researchers developed the device to apply a very gentle electric current to the skin for about 10 minutes. Sodium ions that carry glucose are located in the fluid between skin cells. Glucose is drawn out and flows to the temporary rub-on tattoo. An electronic sensor in the tattoo measures an electrical charge produced by the glucose.

Professor Wang and the team published their study in the journal of Analytical Chemistry. Bandodkar explained more about the flexible device for diabetics.

“The concentration of glucose extracted by the non-invasive tattoo device is almost hundred times lower than the corresponding level in the human blood. Thus we had to develop a highly sensitive glucose sensor that could detect such low levels of glucose with high selectivity.”

Currently, the tattoo for diabetics does not provide a numerical reading; however, scientists are working on developing a way to provide a numeric readout. They are also working on developing an application that is capable of sending information of diabetics in real time using Bluetooth technology.

According to the researchers, the tattoo could be used to measure other important chemicals such as lactate, a metabolite analyzed in athletes to monitor their fitness. This device may also be used to detect illegal drug or alcohol consumption, or to test how well medication is working.

Costing a few pennies and a less painful alternative for managing diabetes, this discreet and non-invasive device is a most welcome advancement for diabetics.

The Best Way to Create a Vision for the Life You Want

The Best Way to Create a Vision for the Life You Want

Creating a vision for your life might seem like a frivolous, fantastical waste of time, but it’s not: creating a compelling vision of the life you want is actually one of the most effective strategies for achieving the life of your dreams. Perhaps the best way to look at the concept of a life vision is as a compass to help guide you to take the best actions and make the right choices that help propel you toward your best life.

your vision of where or who you want to be is the greatest asset you have

    Why You Need a Vision

    Experts and life success stories support the idea that with a vision in mind, you are more likely to succeed far beyond what you could otherwise achieve without a clear vision. Think of crafting your life vision as mapping a path to your personal and professional dreams. Life satisfaction and personal happiness are within reach. The harsh reality is that if you don’t develop your own vision, you’ll allow other people and circumstances to direct the course of your life.

    How to Create Your Life Vision

    Don’t expect a clear and well-defined vision overnight—envisioning your life and determining the course you will follow requires time, and reflection. You need to cultivate vision and perspective, and you also need to apply logic and planning for the practical application of your vision. Your best vision blossoms from your dreams, hopes, and aspirations. It will resonate with your values and ideals, and will generate energy and enthusiasm to help strengthen your commitment to explore the possibilities of your life.

    What Do You Want?

    The question sounds deceptively simple, but it’s often the most difficult to answer. Allowing yourself to explore your deepest desires can be very frightening. You may also not think you have the time to consider something as fanciful as what you want out of life, but it’s important to remind yourself that a life of fulfillment does not usually happen by chance, but by design.

    It’s helpful to ask some thought-provoking questions to help you discover the possibilities of what you want out of life. Consider every aspect of your life, personal and professional, tangible and intangible. Contemplate all the important areas, family and friends, career and success, health and quality of life, spiritual connection and personal growth, and don’t forget about fun and enjoyment.

    Some tips to guide you:

    • Remember to ask why you want certain things
    • Think about what you want, not on what you don’t want.
    • Give yourself permission to dream.
    • Be creative. Consider ideas that you never thought possible.
    • Focus on your wishes, not what others expect of you.

    Some questions to start your exploration:

    • What really matters to you in life? Not what should matter, what does matter.
    • What would you like to have more of in your life?
    • Set aside money for a moment; what do you want in your career?
    • What are your secret passions and dreams?
    • What would bring more joy and happiness into your life?
    • What do you want your relationships to be like?
    • What qualities would you like to develop?
    • What are your values? What issues do you care about?
    • What are your talents? What’s special about you?
    • What would you most like to accomplish?
    • What would legacy would you like to leave behind?

    It may be helpful to write your thoughts down in a journal or creative vision board if you’re the creative type. Add your own questions, and ask others what they want out of life. Relax and make this exercise fun. You may want to set your answers aside for a while and come back to them later to see if any have changed or if you have anything to add.

    What Would Your Best Life Look Like?

    Describe your ideal life in detail. Allow yourself to dream and imagine, and create a vivid picture. If you can’t visualize a picture, focus on how your best life would feel. If you find it difficult to envision your life 20 or 30 years from now, start with five years—even a few years into the future will give you a place to start. What you see may surprise you. Set aside preconceived notions. This is your chance to dream and fantasize.

    A few prompts to get you started:

    • What will you have accomplished already?
    • How will you feel about yourself?
    • What kind of people are in your life? How do you feel about them?
    • What does your ideal day look like?
    • Where are you? Where do you live? Think specifics, what city, state, or country, type of community, house or an apartment, style and atmosphere.
    • What would you be doing?
    • Are you with another person, a group of people, or are you by yourself?
    • How are you dressed?
    • What’s your state of mind? Happy or sad? Contented or frustrated?
    • What does your physical body look like? How do you feel about that?
    • Does your best life make you smile and make your heart sing? If it doesn’t, dig deeper, dream bigger.

    It’s important to focus on the result, or at least a way-point in your life. Don’t think about the process for getting there yet—that’s the next stepGive yourself permission to revisit this vision every day, even if only for a few minutes. Keep your vision alive and in the front of your mind.

    Plan Backwards

    It may sound counter-intuitive to plan backwards rather than forwards, but when you’re planning your life from the end result, it’s often more useful to consider the last step and work your way back to the first. This is actually a valuable and practical strategy for making your vision a reality.

    • What’s the last thing that would’ve had to happen to achieve your best life?
    • What’s the most important choice you would’ve had to make?
    • What would you have needed to learn along the way?
    • What important actions would you have had to take?
    • What beliefs would you have needed to change?
    • What habits or behaviors would you have had to cultivate?
    • What type of support would you have had to enlist?
    • How long will it have taken you to realize your best life?
    • What steps or milestones would you have needed to reach along the way?

    Now it’s time to think about your first step, and the next step after that. Ponder the gap between where you are now and where you want to be in the future. It may seem impossible, but it’s quite achievable if you take it step-by-step.

    It’s important to revisit this vision from time to time. Don’t be surprised if your answers to the questions, your technicolor vision, and the resulting plans change. That can actually be a very good thing; as you change in unforeseeable ways, the best life you envision will change as well. For now, it’s important to use the process, create your vision, and take the first step towards making that vision a reality.
