Static electricity is the imbalance of electrical charges in or on a surface. Static electricity has the potential to fry your computer’s hard drive and completely mess up certain electronics if they are placed on a surface that is a conductor. Many people experience static electricity when they interact with certain objects and end up getting shocked. We wanted to figure out a way or at least give ourselves an idea on what objects have the highest risk of shocking you or frying your computer. We want to create a device that allows us to detect an electric field in order to see how strong of a charge an object has. Our objective is to create a super sensitive electric field detector that will enable us to measure the different charges that objects from the triboelectric series have in order to determine which objects you should stay away from and which are less likely to shock you or an electronic device. Using a breadboard, a transistor and a 100 k? resistor with a 9V battery we will be able to clearly understand and see how powerful an electrical field of an object really is. Introduction Getting shocked happens many times to many different people and it is not exactly the best feeling in the world. Static electricity is the accumulation of electrical charges on a surface produced by the contact and separation of dissimilar materials. In simpler terms, static electricity is created by rubbing two objects that are not good conductors together causing electrons to jump from one object to the other. Some people get shocked more than others but others get shocked simply by touching a doorknob. The reason we sometimes get shocked while making contact with a thing made out of metal is because it has a positive charge but only a few electrons. This makes the electrons we have in our hands jump towards that material causing the electrical shock. Certain materials can hold more electrons than others which is why scientists created the Triboelectric Series. It’s basically a list of materials that helps people understand which two items when combined generate more static electricity. It is ranked from which objects have a greater tendency to become positive and which have a greater tendency to become negative1. Some of the items on this list have the capability of damaging certain electronics especially hard drives. Many computer hard drives have been fried due to being shocked2. Static electricity as low as 10 volts is able to damage a hard drive so we wanted to see what materials have the highest capability of frying a hard drive or shocking people in general. Our objective is to make a device that tells us the changes in the static electricity on our body as we interact with certain items as well as tell us which object has the highest amount of electricity. By getting closer to the electrical field of an object we hope that we will have really good readings on the different changes in static electricity based on distance as well. An electrical field is and electrical property associated with each point in space when charge is present in any form. Using this sensitive field detector will allow us to really pin down what objects cause the greats change of static electricity. This will give us a clearer idea on what objects to avoid to not get shocked and what objects to keep your computer from. ObjectiveThe objective of our project is to create a fully functional electric field detector in order to measure how well different materials hold an electric charge. Hypothesis Our null hypothesis is that the detector will not be able to measure any electrical charge. Our alternative hypothesis is that our detector will in fact be able to correctly read the objects electrical charge. Materials & Methods The materials will we need for this project are:Electronic Sensor Kit- $69.95RulerStopwatchTapeLab notebookSeveral objects from the triboelectric series Methodology In order to create this “Super sensitive Electric Field Detector” we must first get our charge detector circuit. The Hall effect sensor and the transistor will be assembled on a breadboard. When handling the transistor on the breadboard, we must grab it by the plastic case and avoid touching the metal leads. We will insert the transistor leads into holes A1, A2, and A3 with the writing facing towards us. Next we will insert the LED long head into B3, and the short lead into B4. After this is inserted we next insert one lead of 100 k? resistor into C1. Lastly we connect the snap connector to the battery as well as red lead to E2 and the black lead to E4. Once it is built properly we should see a red LED that lights up. you will see that its has two distinct openings. Proposed Analysis In order to collect the data we will separate all of the triboelectric objects in order from positive charges to neutral to Negative. We will then use the electric field detector to determine the change in static electricity between each object. As soon as we rub two objects together we must quickly bring the detector close to the electric field and time how long it takes for the red LED to light up. Once the LED shuts off, we will be able to see how long the object can hold the charge for. We will also measure the distance from the antenna of the detector to where the objects are. This will let us know how large is the electrical field of that particular object and how strong it is. However this might be tricky because the objects might lose charge if we attempt to move them towards the detector using our hands. Once we collected all the measurements and time we will categorize the objects into two groups which consist of Which materials hold the charge for longest? And which generated the strongest electrical field. With this we will figure out which objects have the highest chance to shock you and or fry your computer.
