i need to summarize a literature article for less than a page and its about a shoe taking power from piezo discs

they are three articles and the whole article need to be saummraized not the abstract and in your ouwn words no copying from the article or google. because it is about senior project rechargeable shoe that im going to build up for next semester. if you are not an engineering, you are not familiar with my subject; dont bother yourself cause i will ask you about the subject
