The invention relates to a wireless fingerprint alarm under a body area network environment and particularly realizes that the identity and related information of alarm people can be rapidly positioned and queried under one-finger triggering, and prevents the misoperation and repudiation on the alarm. The wireless fingerprint alarm under the body area network environment comprises a microprocessor, a wireless transmission module, an environment perception module, a mobile communication module, a fingerprint identification module and an alarm device. The wireless fingerprint alarm under the body area network environment is characterized in that the wireless transmission module transmits the collected danger signals from nodes of the body area network or a host node on a human body to the microprocessor, when the information value exceeds the preset value set in the microprocessor, the microprocessor controls the alarm device to give an alarm and remind disease examination; when the alarm needs to be given, the fingerprint identification module collects and verifies fingerprint information, the environment perception module collects the surrounding environmental information, the fingerprint information and the surrounding environmental information are respectively inputted to the microprocessor, and the GPRS / GSM (general pocket radio service) / (global system for mobile communication) module is triggered by the microprocessor to transmit the fingerprint information and the environmental information to an emergency center service station.
