bijoux by Jennifer Broutin


Bijoux is a modular kit to for personalized jewelry that is responsive to people and the environment.  Considerations in the design will include: sound, proximity, temperature, touch, and pressure with output to a tangible light display as the basis for the component design.

Alternate forms created by combining modules

Example of lighting output from light sensor module. As light dims, necklace illuminates.

Early Sketches

First iterations of design

Form of prototype at Midterm

Playing with triangular shapes to form different combinations

Considerations for mechanical/electrical connections and lighting within each module

Testing different materials for mechanical/electrical connection

Different versions of circuit board for each module and battery circuit

Detail of each component enclosure

Beginning of assembly

Cost analysis study


The target group is for technology/design oriented people, all ages – more focused towards females.

Manufacture - Hybrid Approach:

  • The circuit boards and components will be premade and soldered.
  • The exterior enclosure will be 3D printed (this may change).
  • Assembly of each bijoux will be done in house (me).  This will be a low maintenance process: Set preassembled circuit board and components onto bottom of enclosure with adhesive, Add magnets, Snap close enclosure
  • Design of packaging will be done in house (me).
  • Production of packaging/instructions will be done by contract.
  • Packaging and shipment will be done in house (me).
  • Assembly of bijoux system will be customized by the user.

Kickstarter Project with website for custom purchase, additionally sold as starter kits.
