摘要： A wireless sensing device and a method for operating a wireless sensing device are described herein. The wireless sensing device includes a battery power supply and a processor that transmits detected physiological parameters from the sensing device to a monitoring device. when the battery level within the sensing device falls below a minimum threshold, the processor of the sensing device reserves a portion of the battery charge to power an indicator to increase the noticeability of the sensing device. The sensing device can also include an RFID tag that is written to by the processor when the state of charge on the battery falls below the minimum threshold. The RFID tag allows RFID detectors to sense the presence of the sensing device without requiring additional battery power.
