Abstract

This document discusses, among other things, a system and method for detecting biomedical data of a patient. Biomedical data of the patient can be detected using one or more wireless sensors. The wireless sensor can include pyro electric and piezo electric properties and can be coupled to a wireless transceiver to receive the biomedical data. Examples include wirelessly communicating the biomedical data to a base station coupled to a polysomnograph (PSG) machine or a sleep therapy device.
