Researchers have replaced the traditional blood pressure procedure by replicating the folding mechanisms of the leech 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 (ECG)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.

The researchers believe that such robotics provide a future platform or bridge between medical personnel and remote patients with “the potential to play an essential role in the new era of remote healthcare.”
