Abstract

A system includes a mobile computing device, a sleeve, a contact surface, a sensor module, and a telemetry module. The mobile computing device has a first processor within a housing. The sleeve has an internal surface configured to fit the housing. The contact surface is disposed on an external surface of the sleeve. The sensor module is coupled to the contact surface and is configured to generate an electrical signal corresponding to a measured physiological parameter associated with tissue at the contact surface. The telemetry module is coupled to the sensor module and is configured to communicate data corresponding to the electrical signal to the mobile computing device.

Claims
