Razor with chemical and biological sensor

Abstract

A razor has an electrochemical sensor for sensing various characteristics, such as biological, chemical, temperature, humidity, and pressure. The electrochemical sensor is positioned within a razor head of the razor, but may be attached to and enclosed in the razor head housing or attached to a razor blade of the razor. The electrochemical sensor may be positioned at different locations within the housing and on the razor blades. The electrochemical sensor may be positioned such that a sensing surface is exposed to a shaving surface of a patient. The razor may also have various electrical components for processing signals generated by the electrochemical sensor and determining the presence or concentration of a chemical or biological marker. The data associated with the signals may be displayed, transmitted to a separate computing device, or stored in a memory.
