A Mobile Application for Measuring Contact Angles

A Mobile Application for Measuring Contact Angles

Internship Description

Small drops of liquids are ubiquitous in our daily life, for example, morning dew on flowers, leaves and spider webs are some common examples.  Typically, the interface at the solid-liquid-gas contact line forms a contact angle that represents the mechanical equilibrium of the interfacial tensions. In a lab setting, contact angle have been traditionally measured by taking images and using a goniometer. These days, however, image-processing software are routinely employed for accurate and quick estimation of contact angles. Unfortunately, due to the bulkiness of contact angle instruments and their cost proprietary software, experiments are limited to confines of laboratories that can afford them. We would like to change this trend by using smart phones.
We propose to develop a software application for smartphones, which will take input from the mobile camera and calculate contact angles, base diameters, and drop volumes in real-time for real world experiments. The application would be developed in Android as well as iOS platforms. The application will have a user-friendly interface to obtain the contact angles and save and share data. Both specialists and amateur scientists will welcome such an application.​​
