Robots to Check BP

Simon Fraser University researcher Woo Soo Kim has developed a technology by which humanoid robots can check blood pressure. The traditional blood pressure procedure was replaced by replicating the folding mechanisms of leeches in their design of 3-D printable origami sensors. The leech-inspired origami (LIO) sensors can be integrated onto the fingertips of a humanoid-sensing robot.  The LIO sensors integrated onto the robot's fingertips can be positioned on the patient's chest. Blood pressure is monitored and estimated by combining data from electrocardiogram and photoplethysmogram (PPG) readings, as recorded by sensors on the fingers of each hand respectively. Using predetermined algorithms, the signals from the paired sensors can generate a patient's systolic and diastolic blood pressure without using the traditional cuff-based digital sphygmomanometer.
