Session 2: Hardware Engineering - MIPI
I3C: Designing Multi-Sensor Wearables
Saravana Kumar, Soliton Technologies Private Limited
4 p.m. (IST) | 17 November
Wearable health devices—fitness trackers, smartwatches, continuous glucose monitors and medical-grade patches—are among the fastest-growing segments in embedded design. These devices pack an increasing number of sensors (heart rate, SpO2, accelerometer, skin temperature, ECG) into ever-smaller form factors, all while demanding multi-day battery life. The sensor interface bus is a critical but often overlooked bottleneck in achieving these goals.
Most wearable designers today still rely on I2C or SPI to connect sensors to the host MCU. While familiar, these protocols were not designed for the density, power sensitivity, or interrupt-driven nature of always-on sensing. Designers end up with multiple separate buses, extra GPIO lines for interrupts, and inefficient polling loops — all of which cost pins, PCB area, and power. MIPI I3C® was purpose-built to address exactly these constraints, yet its adoption in the wearable space remains limited due to lack of awareness and practical design guidance.
This talk is intended for embedded hardware and firmware engineers actively designing wearable or IoT sensor platforms. Attendees will leave with a concrete understanding of how I3C's in-band interrupts, dynamic addressing, multi-drop bus and low-power modes map directly to real wearable design challenges — and what a migration from I2C to I3C looks like in practice.
SWI3S in Smart Audio Accessories: One Interface to Rule the Headset
Srihariharan Dhandapani, Soliton Technologies Private Limited
4:25 p.m. (IST) | 17 November
The wired audio accessory market—headsets, earbuds, USB-C audio adapters and hearing aids—is undergoing a quiet but significant transformation. Consumers and enterprises expect accessories to do far more than pass audio: They must support active noise cancellation control, firmware updates, biometric sensing and multi-device switching, all over a physical cable. Yet most of today's wired accessories still use fragmented combinations of analog audio channels, proprietary control protocols, and ad-hoc UART or I2C side-channels to manage this complexity.
MIPI SoundWire I3S (SWI3S®), a simple, wired interface for 2-wire serial designed specifically to unify audio data and control signaling for wired accessories. It offers a clean, standardized single-interface solution that replaces the patchwork of protocols engineers currently rely on.
This talk targets embedded firmware and hardware engineers working on audio accessories, consumer electronics peripherals, hearing health devices, and enterprise headsets. It is deliberately introductory yet application-grounded—designed to give engineers enough practical context to immediately evaluate whether it fits their next project.
