Wichita State researchers are looking for participants for NASA-funded human subjects research. The purpose of this study is to assess the functionality and wearability of a newly developed wireless and flexible skin-wearable photoplethysmography device for cardiovascular health monitoring.

For the ambulatory monitoring test, the participant will be asked to wear the skin-wearable device on different body sites (e.g., forehead, chest, wrist and ankle) and conduct physical activities including walking and jogging.

For the lower body negative pressure test, the participant will wear multiple skin-wearable devices on different body sites (e.g., forehead, chest, wrist, and ankle) and place his or her lower body in a lower body negative pressure camber. The chamber pressure will be lowered by 10 mmHg every 10 minutes until the pressure reaches negative 40 mmHg compared to the atmospheric pressure. After the data collection, the chamber pressure will gradually return to the atmospheric pressure. It is totally safe.

You can select one test to participate in. Before conducting the test, the research team will explain the details of the test to get signed consent form.

This study is reviewed and approved by IRB (study# 5192).

• Participants must be age 20 to 35.
• Participants should not have any known cardiovascular diseases.
• Participants should not have low resting blood pressure (less than 100/60 mm Hg).
• Participants should not have mobility or activity difficulty.
• Participants should not have memory problems.
• Participants must shave skin hair if necessary.

For the ambulatory monitoring test, you will receive up to $100 Greenphire ClinCard for your participation.

For the lower body negative pressure test, you will receive up to $200 Greenphire ClinCard for your participation.

Volunteers 65 years old and above are requested for a fall-risk monitoring study May 24 and June 11 at Donald L. Beggs Hall (main lobby). The study is part of a research project funded by the Regional Institute on Aging. The purpose is to develop a wireless and flexible skin-wearable electronic device with motion sensors to identify the fall risk of older adults.

Procedures

• The research team will help participants to put the fall risk monitoring device onto the skin.
• Each participant will be instructed to conduct five types of different daily activities (sitting, standing, lying, walking, climbing stairs, and running) as well as three types of falls (forward, backward and lateral falls).

Time

• This device test is expected to last about 60 minutes for fall risk monitoring and 30 minutes for additional education or paperwork.
• The fall-risk monitoring test will be conducted between May 24 and June 11.

Inclusion and exclusion criteria

• Participants must be age 65 years or older.
• Participants should be able to stand up from a seated position and lay down from a standing position repeatedly at least 10 times and also walk, run, walk upstairs, and walk downstairs continuously at least for five minutes for each activity.
• Participants should not have mobility or activity difficulty.
• Participants should not have severe visual impairment and hearing loss problems.
• Participants should not have cognitive impairment.

Participants will receive $100 Greenphire ClinCard for their participation. You can use the ClinCard at an ATM or like a debit card. Participants must have a valid Social Security number to participate and to receive the payment.
