Housing: Plastic Display Gem Case (Pressed on diaphragm and aluminum retaining ring)

Diaphragm Seal: Super Glue

Visual Indicator: 500um Microbeads placed on top circular nail polish and LDPE base

Membrane Seal: Generic Super Glue

Testing Details: In an idential fashion to our intial test, super glue was placed sequentially on the surface of the LDPE membrane. Carefully, microbeads were poured on top and allowed time to dry. The end result was a thin layer of glass microbeads attached to the surface with the intent to act as a reflective transducer.

Results: Taken by a member of the Stony Brook Volunteer Ambulance Corp (SBVAC), which is in our group, the blood pressure procedure was standardized to the current ideal of the medical community. There was no movement that revealed clear indication of pulse.
