Case Study 1: The Microsoft Band
Manufacturing Advances1. Insert molded Stainless Steel Metal Injection Molding (SS MIMS)
Strict geometric constraints, tight tolerance requirements, and a need for high strength eliminated more traditional forms of manufacturing for a few critical parts
Combining detailed Finite Element Analyses (FEA) with vendor research, SS MIMS process was selected and designed for in order to provide a successful substrate. ABS/PC is then shot onto the substrate to provide more reliable profile accuracy and a TPE-compatible interface
Working with MIMs vendors and clever design, part cost was able to be brought down to acceptable large-scale levels

Case Study 1: The Microsoft Band
Manufacturing Advances2. Integrated Flex Circuit
Waterproof, sweatproof, and safety requirements demanded creative solutions for Flexible Printed Circuit (FPC) and battery integration
Insert molding directly to the FPC allowed contact potting and gasket sealing with ease of assembly, high positional accuracy, and a flexibility in materials

Case Study 1: The Microsoft Band
Manufacturing Advances3. Complex Sheet Metal Substrates
The main band substrate provides a complex yet critical “backbone” to support and locate all other subassemblies of the device
More expensive and fragile techniques have been common among competitive products but using thin, spring-hardened sheet metal allowed for design complexity, excellent feature accuracy, and high strength at a very low cost

Challenges1. Compact size
2. Water and sweat resistance
3. Industrial design
4. Human factors/ Ergonomics
5. Safety
6. Durability
Solutions1. New manufacturing processes, metal instead of
plastic for backbone, FPC and cross-team cooperation

Needs in Technology• Low Power Sensors
Power technology moving in the right direction. Sensors still consume significant power: 50% more than CPU (and CPU is oversized for this application due to memory requirements).
• Low cost position measurement system Especially one that works at low frequency. The orientation
problem is adequately solved, but position only works for cyclic motions of sufficient speed.

Looking to the Future: From Sensing to Affecting
• Very limited ability of today’s products to manipulate the real world
• The next wave of smart products need to manipulate their environment based on their sensors
• Key challenges: Low cost & energy efficient manipulators: motors, solenoids, etc.
Manipulator + feedback sensor integration
Energy distribution / energy harvesting
Easy-to-use security
• Majority of “smart products” today are centered on internet connected sensors
• Products great at gathering data from the real world
