血液的压力传感内裤
Blood pressure is not hard to measure, but the necessary equipment for clinically accurate measurements – a cuff, a pump, and stethoscope or electronics – is bulky and heavy.血液的压力,并不难的措施,但必要的设备,为临床精确测量-袖口,泵,听诊器或电子-是体积大而沉重。
However, researchers have recently found that a person’s “pulse wave velocity” is closely linked to blood pressure.不过,研究人员最近发现,一个人的“脉搏波速度”是紧密相连的血液压力。 This is the rate at which the pulse pressure wave passes through the blood circulatory system.这是率在哪个脉冲压力波通过血液循环系统。
Sensors sewn into the waistband of a person’s underpants can measure the rate of this wave, consumer electronics company Philips has discovered, and could be used to calculate blood pressure for as long as the garment is worn.传感器车缝到腰带一个人的内裤可以衡量率这一波,消费类电子产品公司飞利浦已经发现,并且可以用来计算血液中的压力,因为只要制衣磨损。
Each sensor continually measures the electrical impedance of the tissue beneath it – a property that changes as the pulse wave passes by.每个传感器的措施,不断电阻抗的组织,它的下方-财产的变化,作为脉冲波经过。 A pair of such sensors can calculate the speed of the pulse wave by timing how long it takes to travel from one sensor to the other.一对这种传感器可以计算的速度脉冲波的时间需要多久才能旅行,从一传感器到其他。
Once calibrated with a conventional blood-pressure reading, the electrodes can then give accurate blood-pressure readings, while the wearer enjoys the comfort of their own underpants.一旦校准与传统的血液压力读,电极可以,然后准确的血液压力读数,而在穿衣享有舒适的自己的内裤。
现在在考虑的东西关系到了医药这个领域,奶牛就把一些很有意思的发上来,或者这些也会给你带来一些灵感
