Is this a functioning medical device on the market?

No. SYNAPSE / BAND is a speculative design engineering concept illustrating LOOP's capabilities in wearable ergonomics, micro-CAD, and biocompatible material CMF.

Does LOOP design for human factors?

Yes. Anthropometric research and ergonomic volume studies are foundational steps in LOOP's product development process.

SYNAPSE / BAND

Medical-grade biometric wristband with continuous arterial pulse wave sensing

IN PLAIN ENGLISH:

A medical-grade biometric wristband that measures arterial pulse waves through dry titanium sensor contacts.

CRITICAL SPECIFICATIONS

PRODUCT:Biometric Wristband

MATERIAL:Fluoroelastomer (FKM) & Grade 5 Titanium

DIMENSIONS:Band width 22.0 mm × Core thickness 5.2 mm

TOLERANCE:Electrode sensor seating ±0.015 mm

SOFTWARE:Rhino 8, SolidWorks, KeyShot

BIOMETRIC WRISTBAND // 3D SOLID CAD

MATERIAL: Fluoroelastomer (FKM) & Grade 5 Titanium

TOLERANCE: Electrode sensor seating ±0.015 mm

DIMENSIONS: Band width 22.0 mm × Core thickness 5.2 mm

02 // PHYSICAL CONTEXT

THE PHYSICAL PROBLEM.

Standard fitness trackers either pinch the wrist, lose optical skin contact during movement, or have fragile plastic buckles that break under tension.

SYNAPSE / BAND utilizes an elliptical spring-tensioned band with an auto-cinching magnetic clasp, maintaining optimal 12 kPa sensor pressure on the radial artery.

03 // SCULPTING

FORM DEVELOPMENT & CLASS-A SURFACES.

Derived from 3D anatomical scans of 500 wrist profiles to establish an organic curve that floats over the ulnar styloid bone without pressure points.

Zero Visual Seam

04 // PARAMETRIC CAD

SOLID CAD ARCHITECTURE.

Combines elastomer overmolding with an internal titanium skeleton. The flexible sensor array is encapsulated inside a liquid silicone rubber (LSR) envelope.

Five multi-wavelength photodiode clusters arranged in a circular array, shielded from ambient light interference by a micro-machined titanium bezel.
