Detachable apparatus for measuring bioelectric signal utilizing mobile phone

PURPOSE: A detachable apparatus for measuring a bioelectric signal utilizing a mobile phone is provided to improve the convenience of usage by installing the detachable apparatus for measuring the bioelectric signal within a power unit of the mobile phone. CONSTITUTION: A housing(10) is comprised of a detachable rechargeable Li-polymer battery on a back of a mobile phone, a liquid crystal panel(12), and a connecting terminal(13). Plural metal electrodes(14) are projected-installed on an external surface of the housing(10) to detect an electromyogram. A skin-contact-typed recording electrode(20) is connected to the connecting terminal(13) of the housing(10) to detect an electrocardiogram of a chest. A biological signal recording unit analyzes an amplitude and a frequency of digitized electromyogram signal and electrocardiogram signal to display the analyzed result on the liquid crystal panel(12).
