Outcome Measures

Primary Outcomes (3)

  • Mean Comfort Level of Wearable Sensors

    A questionnaire about the comfort of the wearable sensors will be measured using the Likert scale, which ranges from 1 to 5 and is used to measure attitudes and perception changes about the our sensor. The minimum value 1 represents "strongly disagree" and the maximum value 5 represents "strongly agree", thus higher scores represent a better outcome.

    Questionnaire completed within 96 hours after device application.

  • Mean Safety Level of Wearable Sensors

    A questionnaire about the safety and reactions to the wearable sensors will be measured using the Likert scale, which ranges from 1 to 5 and is used to measure attitudes and perception changes about the safety of our sensor. The minimum value 1 represents "strongly disagree" and the maximum value 5 represents "strongly agree", thus higher scores represent a better outcome.

    Questionnaire completed within 96 hours after device application.

  • Mean Agreement Over Time of Physiological Parameters between Newly-Fabricated Wearable Sensors and Approved Devices

    Signals from the approved medical devices will measure tissue mechanics, heart rate, respiration rate, blood flow, and pulse oxygenation measurements and these data will be compared to the signals from our sensors. The difference over time will be measured on a scale from a minimum of 0 and a maximum of 1, with 0 being the best outcome and representing the lowest difference between the sensing data from the different devices.

    Through study completion, an average of 15 minutes.

Study Arms (2)

Wearing Biosensor Before & After Exercise

EXPERIMENTAL

Each study participant will wear the bioelectronic sensors during a slow deep breath. Participants will wear the sensors and devices for 15 minutes before and after a brisk 6-minute walk.

Device: Multi-modality Noninvasive BiosensorDevice: OximeterDevice: Portable Blood Pressure MonitorDevice: Vicorder Pulse Wave Velocity Monitor

Wearing Biosensor for an Extended Period

EXPERIMENTAL

Each study participant will wear the bioelectronic sensors during a slow deep breath. Participants will wear the sensors and devices continuously for 2 hours.

Device: Multi-modality Noninvasive BiosensorDevice: OximeterDevice: Portable Blood Pressure MonitorDevice: Vicorder Pulse Wave Velocity Monitor

Interventions

The wearable sensor devices will be placed on the finger, wrist, temple, subclavian, arm, neck, and thigh of the participant and will provide continuous tissue mechanics, heart rate, respiration rate, blood flow, and pulse oxygenation measurements continuously throughout the experimental period.

Eligibility Criteria

Age18 Years - 99 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Individuals with ages between 18 and 99.
  • Healthy individuals (not known to suffer any significant illness relevant to the proposed study).

You may not qualify if:

  • Pregnant or lactating.
  • History of active (clinically significant) skin disorders that make skin vulnerable to contact conventional electronic devices.
