    a new study has reported a way to monitor human life characteristics without direct contact with the skin. The technology promises to monitor multiple people simultaneously and provide a cost-effective and gentle way to monitor inpatients.
    it is important to measure patients' life characteristics when caring for them, but current methods often require direct contact with the skin, which can cause discomfort and mobility problems for patients.
    and Edwin Kan of Cornell University in New York have created a new method that directly converts the patient's external and internal movements into radio frequency signals. The technique, known as near-field-to-dry sensing, works with radio frequency identification (RFID) tags attached to fabric antennas. Antennas are placed near the skin, such as shirt pockets or cuffs. The phase of the electromagnetic signal is sensitive to the distance between the RF power supply and the receiver and can be used to evaluate external chest movements. The amplitude of the signal is less sensitive to such changes and can therefore be used to sense movement in the body.

    , the researchers say the technique could be used to monitor heart rate, blood pressure and breathing rate and breathing difficulty. (Source: Feng Weiwei, China Science Journal)
