Measurement and Analysis of Pulse Wave Using a Clamping Pulsimeter Equipped With Hall Effect Device

Continuous Blood Pressure Measurement From Invasive to Unobtrusive: Celebration of 200th Birth Anniversary of Carl Ludwig

“…Likewise, magnetic sensing (e.g., magnetic PPG transducer or magnetic Hall) can detect the pulse wave through the minute magnetic field change in the permanent magnet caused by arterial pulsation. Features are then extracted from the collected pulse wave, and BP is derived using the linear regression method [70,94].…”

“…Another reported BP meter was developed with optical sensors using the "Phase Shift Method," by which the intrinsic arterial waveform can be traced through compensating the phase difference between the phase of the incident wave and the phase of the reflected wave [97,98]. Other cuffless blood pressure (BP) approaches: (a) ultrasound and pulse transducer [70]; (b) magnetic Hall for BP monitoring [94]; (c) tissue informative mechanism for wearable BP monitoring [96]; and (d) phase shift method [98].…”

Magnetic Micro and Nano Sensors for Continuous Health Monitoring

“…20% for 13 patients with normal or high blood pressure. Another pulsimeter that worked using a Hall effect device was described by Son et al, who measured pulse rate and blood pressure [105]. Jones et al applied a Hall effect sensor in a splint used to inhibit the movement of an arthritic hand [103].…”

Design and Analysis of Dual Hall Position Sensor with Automatic Direction Recognizing and Pre-Positioning Function

“…1. On an electric semiconductor wafer, a magnetic field Bz is perpendicular to the wafer, a voltage will be generated on both sides of the wafer [8]. According to the principle of the sensor, the output signal is very sensitive with the distance between magnet and Hall device.…”
