Low-cost Portable Impedance-based Biosensor for Tuberculosis Test

Tuberculosis (TB) is one of the deadly diseases in low- and mid-income countries. Currently, X-ray and TB culture tests are standard tests, but they suffer from various limitations. For instance, an X-ray requires large & expensive equipment while TB culture test takes a long time. As sensor technologies get more advanced, portable and low-cost diagnosis TB test assays become more desirable. Our proposed palm-size device required a urine sample of 40 mL, and it takes 20 to 30 minutes to obtain results. The battery-powered device is ease-of-use and costs less than $2 for each test. Such devices can be very beneficial to patients, especially those who live in Africa.
