Technology

Using the PDID sensor technology, the charm is inserted into the drink. Using the components of light, current, and temperature the sensor is able to detect the contents of your drink. A drink that has high traces of red, yellow or orange, most likely has a stimulant in it. Colors of blue and green indicate a tranquilizing effect. The current of a drink is less fluid and ions move less freely when a drug is introduced into a liquid such as alcohol. In addition, date rape drugs often increase the temperature of drinks making it another indicator a drink has been tampered with. This is hard to see from the naked eye, so a device is needed to detect it. From there, a microcontroller, such as an Arduino, will be used to transmit that data from the sensor to the app. When the information is in the app, the app uses a database to search and compare the contents of what was found in the drink in comparison to what elements are in common date rape drugs such as, Rohypnol and Zolpidem. Once the information has been compared, the microcontroller will send a signal back to the sensor. If the database detects date rape drugs, then the sensor will turn red. If it does not, then the sensor will illuminate with a green light. In addition to that, a text message will be sent to your phone notifying the user whether or not their drink has been tampered with. If a drug has been placed in your drink, your emergency contact will be notified with what has been placed in your drink in addition to your location. This will be able to happen because before using the app, users will input their emergency contact and allow location services to be turned on. Lastly, we will use kinetic charging to provide power to this device. Kinetic charging uses piezoelectric crystals to convert body movements into electric charges. This limits the need to charge the device.
