Mild reactions to electric shocks are brief tingles and jolts, but more severe reactions can cause more severe pain and even burns. The shock also can trigger continuous contraction of muscles, rendering the target immobilized and unable to let go of the shock pen. Shock pens are not intended to be used on those who use pacemakers or other electronic devices in their body.
They are also not recommended for people with heart problems or epilepsy. Shock pens are not to be used on children, and children should not be allowed to use or play with shock pens, even under adult supervision. Her work has been featured in several national magazines.

Most likely this gadget has a piezoelectric element in it, which generates a large voltage at extremely tiny current when the device is activated. You feel a shock from it but it's not generally harmful. Similar technology is used in gas barbeque igniters.
The watch batteries could be used to source a voltage multiplier circuit of some form to generate the shock potential. The heat-shrunk component could be an inductor to which a DC current is applied then interrupted to generate the high voltage, or could be a capacitor. Sign up to join this community.

Internal picture: EDIT: Merged question from Trever Thompson Help here would be greatly appreciated: This question has been asked several times on this site and elsewhere, and it seems as if the posters became satisfied with inaccurate answers.
What I know: The device behaves as follows: When the pen is held and the button is pressed a mildly painful electric shock is felt. After about 3 seconds, the pain gradually decreases until it is not longer felt. Upon releasing and pressing again the full shock is felt once again, even if only released for the slightest moment.
The button and grip are the electrodes. It uses 4 1. The secondary uses extremely thin wire. It apparently is an autotransformer, as it has three leads and is wrapped around one ferrite column. What I think I know: I measured the frequency on the primary with a primitive oscilloscope.
It was equal to a couple hundred hz, which is reasonable considering the pain of the shock. This may be possible as I have discovered high capacitance low voltage smd caps. The primary inductance would have to be several mH. The turn ratio would I believe have to be at least This surprised me because I read that most autotransformrs have a low ratio. I then encountered higher ratio custom ones which is more reasonable if varying wire gauges are used.
What I want to know: What the white component is. Is it merely a capacitor? Does it serve other functions? How on earth does this circuit work. It seems so simple and then again I can't explain or emulate its behavior accurately in a simulator Help will be greatly appreciated, as this has kept me occupied for a long time. Community Bot 1.
