Abstract
Aspects of this disclosure describe a test strip that may include a sample input, assay circuitry, signaling circuitry, impedance circuitry, and/or energy harvesting circuitry. The sample input may be configured to receive a sample, such as a fluid sample. The assay circuitry of the test strip may be configured to perform an assay on at least a portion of the fluid sample. The signaling circuitry of the test strip may be configured to provide a modulated signal based on an output of the assay. The impedance circuitry of the test strip may be configured to present impedance changes to a touchscreen of an electronic device in accordance with the modulated signal. The test strip can then communicate data of the output of the assay (e.g., test results) to the electronic device using the touchscreen of the electronic device.
