The market for wireless sensor networks is growing rapidly, but it’s still somewhat restricted by the existing batteries with short lifetimes. Introducing a virtually infinite alternate green source of power to the conventional energy sources will considerably expand WSN and other similar applications in near future, but it may still take a few years time. MEMS vibrational micro power generation is one method that has seen a drastic increase in power harvesting usage over the last couple of years, and this methodology certainly looks quite promising, to say the least.

Many new-fangled devices are tapping the vibrations in their surroundings to produce useful energy. Several wireless and sensor technologies present very few power requirements so that just a few microwatts or power of even lesser magnitude are adequate to measure and transmit small quantities of information to a dashboard or receiver close by.

VEH (Vibrational energy harvesting) with MEMS is tremendously helping in achieving the eventual objective of battery-free, wireless, autonomous sensing, testing, and reporting.

Of late, powering wireless networks and sensors with such vibrational power sources has been considered for industrial applications and is undergoing field testing in several applications wherein thermal or solar energy sources can’t be utilized. Few of the industries where it finds use include structural monitoring, industrial process control, roads & bridges, appliances, human power, environmental, machine monitoring, aerospace, automotive, and home automation.

Several varying MEMS VEH processes and device designs have illustrated that adequate power production is possible easily, in order to charge a battery or beam data wirelessly by mainly using piezoelectric or electrostatic techniques; electromagnetic methods are also used rarely. Usually, a moving spring is utilized to function and return maximum power at particular frequencies.

MEMS technologies and devices have assembled and changed such vibrations into useful electrical energy, provided that these vibrations occur in a narrow frequency range. But a majority of the devices operate at different speeds and feature distinct vibration profiles.

Vibrational Confrontations

The challenges faced by harvesters of vibrational energy mainly revolve around finding the ideal device that can be utilized for a particular frequency and deriving adequate power from those frequencies for sufficiently long intervals of time. The only goal of vibration harvesting is certainly finding a broad-frequency or a device whose power harvesting capability does not fall steeply near a resonant frequency, so as to keep capturing power with the change in vibrations. However, it turns out to be a costly affair to make use of an array of harvesters with each of them being tuned to different frequencies.

Innovative Solutions

The designs of MEMS VEH are improving; a recent report discussed the strategies that were publicly accessible in order to extend the vibrational frequency range of micro-range VEH, including but not limited to –

• Tuning the system periodically with electrical or mechanical techniques, consuming power continuously or intermittently
• Bandwidth widening by using a mechanical stopper, a generator array, bi-stable structure, or nonlinear springs.

Piezoelectric tuning along with an active powered feedback loop was adopted by the researchers at CEA-Lab for Electronics & Information Technology in France. They discovered that it could automatically tune the system to enhance the bandwidth by almost one-third of the resonant frequency, costing less than 5µ watts. The non-linear springs that were implemented could improve the vibration amplitude and frequency range.

With such creative solutions, MEMS vibrational micropower generation devices have turned out to be a fantastic option for commercial usage, and are certainly expected to become one of the most promising technologies of the future.

Pinterest is an electronic scrapbooking website that was specifically created for people to post up content that describes their favorite things through pictures and comments. Much like traditional scrapbooking, Pinterest is a great way for a person to creatively express the events or topics that are most important to his or her life, only this information can be shared with a large group of people. Pinterest is also a great marketing tool for companies or individuals who want their product or service to gain exposure. If you have been thinking about creating your own Pinterest page, or even if you already have one, here are some tips to help you get the most out of Pinterest.

1. Find Friends
One aspect of Pinterest that many people forget is the fact that it allows you to find friends to exchange your information with. When they see your pictures and topics of interest, it may encourage them to research something they knew nothing about previous to reading your Pinterest page! The same goes for you – once you check a friend’s Pinterest page, that person’s inspiration may encourage you to discover further interests of your own.

2. Keep It Updated
Pinterest is an ongoing project that is constantly changing and evolving. Your likes may change from day to day, and by updating your Pinterest page, you can stay fresh and relevant. While it’s ok to emphasize a few niches or interests, it’s good to keep your overall feed wide & varied to make the most impact.

3. Business Exposure
Want to advertise your business or service in a way that has the potential to reach thousands of people? Well, there is no better online medium than Pinterest. If you own a business or provide a service, advertising your company and its services on Pinterest can gain your company great exposure – likely at little or no cost.

5. Use Facebook
If you want to gain a following of Pinterest fans, you will want to update your Pinterest activities on Facebook. Facebook is a social media that most people are aware of, and it is a great place to promote your Pinterest page, especially since many people still haven’t heard of the wonder that is Pinterest. There is even a way to connect Facebook to Pinterest so that anytime you post on Pinterest, that information will be given on Facebook.

6. Marketing
Pinterest is a great way to market certain products. In fact, many business owners conduct contests to attract more people to their Pinterest page. The more people who repin your business or service, the more people that know about what it is you are attempting to market. Of all social media sites available on in worldwide web, Pinterest is quickly becoming the online marketing tool of choice because of its ability to reach a wide range of people.

Pinterest is a new, yet exciting way for both personal scrapbookers and business people looking for the perfect marketing tool to express themselves or bring attention to a business or service. With Pinterest not only can a person enjoy sharing the things they like with friends, but a company can generate a lot of business. Pinterest is a great place for electronic scrapbooking and business promotion.

Would you like a recipe, if it doesn’t contain salt? Of course not, as it is one of the most important ingredients of food. So does ‘Keywords’ for Search Engine Optimization. This is the reason, that researching keywords is very crucial for your online marketing, as this is the weapon that is used in all kinds of website campaigns. Research for keywords means that you’re actually researching about your customers, as in which potent words they have been using to reach you.

We have gathered a few methodologies for quick research of the suitable keywords and here you are:

Obtain the Keywords:

Google AdWords is usually, the pit stop for the analysts to conduct research on keywords. Let us illustrate a search for a word called ‘shaving’ and see how does this tool work for us. On the left side of the screenshot, you can see a field called “All Categories”, this narrows down your navigation by providing you with certain categories you’re looking for. Once you’re satisfied with the search selection, go for downloading the keywords as CSV in Excel sheet format. You carry on this research with words, phrases, or even sentences.

Have an eye on the frequency of searches:

After the CSV Excel file is downloaded, modify it so that you are left with two main important columns called ‘Global Monthly Searches’ and ‘Estimated Avg. CPC’. Now the question that arises is: how do these two columns help?

Global Monthly Searches

This column shows us the number of times this keyword was searched. If it was never searched for, then it is better you try out some other way to get a better keyword.

Estimated Avg. CPC

This column shows the commercial value of a particular keyword. The higher the value is, the more will be the worth of the keyword. This value is important for third-party businesses. But, if a site is selling its own products, then this column may not hold much importance.

Find your Rival Pages

Till now a good job has been done and you were confined to your province. This is not enough if you want to outsmart your rivals. Use each of the keywords procured by you, to find who your rivals on the search engine listing are. The most common search engine used for this purpose is Google.com. So go to Google, type the keyword, and hit search. This will give you the list of searches for the keyword. Few keywords may have fewer rival pages, which you have to find on your own.

If you go to the left side of the pane of Google, you can find the search tools, under that you get an option called “Past Week”. If you click on that, you get all the searches of last week which signals more significance and you can work accordingly, towards your online business goal.

These practices will give you a better idea of wrapping up with suitable keywords, which you need to pursue in order to generate business. Remember, if your website is targeting inappropriate keywords, then your company value will never rise in the online market.
