If you’re like me, a lard ass who needs to check his blood all the time, then you’re in luck. There is underwear that checks your blood pressure and I even like the color. Using a sensor attached to the waste (good luck rocking a belt), the underwear measures your pulse and calculates blood pressure from there, ultimately letting you know how out of shape you are:
Each sensor continually measures the electrical impedance of the tissue beneath it – a property that changes as the pulse wave passes by. 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.
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.
And enjoy the comfort of our own underpants, we will.
