Abstract: An implantable, wireless cardiac hemodynamics monitor system includes a bio-sensing module and a wireless electronic subsystem. The bio-sensing module is implanted in a heart or an artery of the mammal subject to continuously monitor cardiac functions of the mammal subject. The wireless electronic subsystem is implanted between a fat layer and a dermis layer of a skin of the mammal subject and electrically connected to the bio-sensing module through insulated flexible wires. the wireless electronic subsystem is wirelessly communicated to an external wireless power transfer (WPT) module and an external user interface module. In operation, the wireless electronic subsystem is used to wirelessly receive power transferred from the external WPT module, and provide the power to the bio-sensing module; and to obtain sensing signals of the cardiac functions monitored by the bio-sensing module, and wirelessly transmit the sensing signals obtained to the external user interface module.
