Google’s latest patent describes using ultrasonic bathtubs, pressure sensing toilet seats and other devices to monitor people’s cardiovascular* health.

    The pressure and electrical-sensing mat is designed to sense a pulse wave velocity* of the person’s blood, which will measure their artery* health.

    The mat may also measure a heart’s electrical conduction system through electrical impulses generated by the polarization and depolarization of cardiac tissue*, and then translates this to a wave form.

    The pressure sensing toilet seat would also be used to measure the patient’s blood pressure, as well as monitor the individual’s health through their bowel movements*.

    Another device is a color-sensing mirror that records colors in a person’s skin to determine a photo-plethysmogram*, which measures variations in a size or color of an organ or limb.

    The ultrasonic bathtub is setup to generate high-frequency* sound waves and gather an echo from these waves in order to investigate the internal body structure — blood flow, tissue movement, and could create 3-D measurements of the internal structure.(SD-Agencies)
