Your Timeless Guide
Embedded systems for devices people wear and carry. From payment rings and fitness trackers to clinical monitors and electronic health cards, built on Infineon silicon.
Complete wearable and personal device solutions, from firmware to cloud, powered by Infineon hardware.
Compact, secure wearable payment and authentication devices built on Infineon SECORA Connect NFC controllers and PSoC BLE SoCs. We develop the firmware that ties together contactless payment applets, BLE connectivity, and ultra-low-power management for devices where every microamp matters and every square millimeter of PCB space is contested.
Full-stack embedded systems for smartwatches and fitness devices using Infineon PSoC Edge MCUs, AIROC Wi-Fi/Bluetooth combos, and XENSIV MEMS sensors. We build the firmware layer that coordinates ML inference on-device, manages multi-radio connectivity, handles sensor fusion, and keeps power consumption low enough for multi-day battery life.
Continuous health monitoring systems built on Infineon's low-power BLE and secure microcontroller platforms. We engineer the sensor acquisition pipelines, real-time signal processing, encrypted data transmission, and cloud ingestion layers that clinical-grade wearable devices require to pass regulatory review.
Secure health credential systems using Infineon TEGRION and SECORA ID security controllers. We build the card operating systems, applet frameworks, and backend provisioning infrastructure that governments and insurers need to issue, manage, and authenticate health credentials at national scale.

Infineon builds the silicon that goes into wearable devices. We build the firmware, software, and infrastructure that makes that silicon do something useful. Our engineering team works with Infineon's PSoC, AIROC, SECORA, and OPTIGA product families to turn evaluation boards into shipping products.
Every wearable project starts with trade-offs. Battery capacity versus feature set. Radio range versus power draw. Sensor count versus PCB real estate. Form factor versus thermal envelope. We work through these constraints with the hardware team, select the right Infineon components for the application, and design the system architecture around what the physics actually allows. PSoC Edge for devices that need on-device ML. SECORA Connect for anything with payment credentials. AIROC combos when the device needs both Wi-Fi and Bluetooth. OPTIGA when the threat model demands a hardware root of trust.
The firmware in a wearable device is the most performance-sensitive code most people never think about. It manages the radio stack, runs the sensor acquisition loops, handles the power state machine, and on newer platforms runs ML inference without draining the battery in four hours. We write this firmware against Infineon's hardware abstraction layers, using their driver libraries where they're solid and writing custom drivers where they're not. BLE profiles, Wi-Fi provisioning, NFC transactions, MEMS sensor calibration, and the power management that ties it all together.
Wearable devices that handle payment credentials need EMVCo certification. Medical wearables need FDA or CE marking. Consumer devices need FCC and Bluetooth SIG qualification. Health cards need Common Criteria evaluation. We manage the certification process from test plan through lab submission through the inevitable rounds of remediation. We've learned which test labs are faster, which failure modes are most common, and which design decisions made in month one cause certification delays in month eight.
Where wearable technology and personal devices deliver value
Wearable payment devices with NFC-based transaction processing, tokenized credentials, and companion app management. Full lifecycle from provisioning to deactivation.
Multi-sensor health monitoring with on-device ML for activity classification, sleep staging, and anomaly detection. Continuous data capture with weekly charging cycles.
Continuous vital sign monitoring for remote patient management. Medical-grade accuracy, encrypted data transmission, and integration with hospital EHR systems.
Electronic health cards that store patient records, prescription history, and insurance credentials on tamper-resistant security controllers with contactless interfaces.
Single-use medical devices with BLE connectivity for glucose monitors, drug delivery patches, and diagnostic wearables. Authentication to prevent counterfeiting.
NFC and BLE credential systems embedded in wristbands and rings for building access, event management, and identity verification without pulling out a phone.
What changes when the firmware team and the hardware partner work as one
One engineering team from the firmware running on the Infineon MCU to the cloud platform processing the data. No handoffs between vendors, no gaps in the stack where problems hide.
EMVCo for payment wearables. FDA/CE for medical devices. Common Criteria for health cards. FCC and Bluetooth SIG for consumer products. We've been through each of these certification paths and we know where the delays come from.
Direct engineering relationship with Infineon's wearable and security divisions. Early access to new silicon families, reference design collaboration, and pre-certification support that accelerates time to market.
Battery life isn't a spec sheet number. It's the result of thousands of micro-decisions in firmware: when to wake the radio, how long to hold a sensor sample, which power mode to enter during idle. We optimize at the register level because that's where the microamps are.
Wearable devices are among the hardest embedded systems to ship. The constraints are relentless: tiny batteries, small antennas, limited thermal headroom, regulatory requirements that vary by market, and users who expect the thing to work flawlessly for years. Most wearable projects that fail don't fail because the idea was wrong. They fail because the engineering underestimated the distance between a working demo and a certifiable product.
In a wearable device, power management isn't a subsystem. It's the system. Every peripheral, every radio transaction, every sensor sample has a power cost, and the budget is measured in milliamp-hours. We design the firmware power state machine before we write the application logic, because the power architecture constrains everything else. Infineon's PSoC and AIROC platforms provide the low-power modes, but the firmware has to use them correctly, and "correctly" means differently for every product depending on the use case and user behavior.
NFC antennas in a ring have different constraints than BLE antennas in a watch. Both have different constraints than a medical patch that needs to maintain a reliable link through variable moisture and body movement. We work with Infineon's RF reference designs as a starting point and then optimize for the actual mechanical envelope, material stack, and regulatory emission limits of each product.
A wearable device that processes payment credentials needs EMVCo type approval. A medical wearable needs FDA 510(k) or CE MDR classification. A health card needs Common Criteria evaluation. A consumer wearable needs FCC Part 15, Bluetooth SIG qualification, and potentially SAR testing. Each of these has its own timeline, test lab requirements, and failure modes. We plan the certification path at the start of the project, not at the end, because design decisions made early have outsized impact on certification outcomes.
Whether it's a payment ring, a clinical monitor, or a health credential system, we can walk you through our reference architectures and what we've learned shipping these products with Infineon hardware.
