Application: Systems and methods for calibrating dry electrode bioelectrical impedance sensing (Patent ID: US20230337929A1)

The patent filed by Terumo Corp. describes systems and methods for calibrating dry electrode bioelectrical impedance measurements for ambulatory and long-term use. The wearable device includes stimulation and sense electrodes, a signal generator, a current sense resistor, and a controller that switches between normal, shorted, and reverse modes to determine calibrated bioelectric impedance based on voltage differences and current measurements. The calibrated bioelectric impedance is calculated using specific formulas involving voltage differences, ratios of voltages, and current measurements across the current sense resistor.

The wearable device can also operate in a reverse mode to determine additional bioelectric impedances, which are then used to calculate the calibrated bioelectric impedance as an average of the multiple measurements. The measurement apparatus functions similarly to the wearable device, utilizing the same components and modes of operation to determine calibrated bioelectric impedance. Both devices use dry electrodes for sensing, providing a convenient and efficient method for measuring bioelectrical impedance in a variety of settings.
