Edge AI & Sensing

Edge AI & Advanced Sensing — Managed End-to-End

Edge AI is the deployment of machine learning inference directly on embedded devices — microcontrollers, FPGAs, and dedicated neural processing units (NPUs) — without sending data to the cloud. This enables real-time decision-making with sub-10ms latency, complete data privacy (no data leaves the device), and operation in disconnected or bandwidth-constrained environments.

Through our partner network, Inovasense manages Edge AI projects optimized for on-device inference, supporting frameworks including TensorFlow Lite for Microcontrollers (TFLM), ONNX Runtime, Edge Impulse, and ExecuTorch, deployed on ARM Cortex-M, RISC-V, and FPGA-based platforms.

Why Edge AI Over Cloud AI in 2026?

The convergence of three forces makes Edge AI the dominant architecture in 2026: the EU AI Act requiring risk classification and documentation of AI systems, data sovereignty regulations (GDPR, NIS2) restricting data transfers, and NPU hardware maturation making on-device inference cost-competitive with cloud APIs.

Factor	Edge AI	Cloud AI
Latency	<10 ms (on-device)	100–500 ms (network dependent)
Privacy	Data never leaves device	Data transmitted to third-party servers
Bandwidth cost	Zero (local processing)	Significant (continuous streaming)
Reliability	Works offline	Requires internet connection
Power	µW–mW range (TinyML)	Watts (GPU servers)
Per-inference cost	Zero (hardware is fixed cost)	Per-API-call billing
AI Act compliance	Simplified (local, auditable)	Complex (third-party processing)
Model updates	OTA to device	API version management

When to choose Edge AI: Industrial anomaly detection, predictive maintenance, visual inspection, autonomous navigation, environmental monitoring, wearable health, counter-UAS, and any application where latency, privacy, EU AI Act compliance, or connectivity constraints make cloud processing impractical.

On-Device AI Trends (2026)

Small Language Models (SLMs) on Edge

The emergence of sub-1B parameter language models (Phi-3 mini, Gemma 2B, SmolLM) enables conversational AI on edge devices:

• Audio-to-text — Whisper Tiny/Base running on Cortex-M85 with Ethos-U85 NPU
• Text generation — 0.5–2B parameter models on application processors with 1–4 GB RAM
• RAG on edge — Retrieval-augmented generation using local vector stores for domain-specific knowledge

Multimodal Fusion

Combining vision, audio, IMU, and environmental data in a single inference pipeline for richer context — e.g., combining acoustic anomaly detection with vibration and thermal data for industrial predictive maintenance.

Sensing & Sensor Fusion

Projects deliver complete sensing systems that combine multiple sensor modalities for higher accuracy and contextual awareness:

Sensor Integration

• Environmental — Temperature (±0.1°C accuracy), humidity, pressure, air quality (VOC, PM2.5/PM10)
• Motion — 9-axis IMU (accelerometer + gyroscope + magnetometer), high-g shock sensors
• Optical — Time-of-Flight (ToF) distance, ambient light, spectral analysis (NIR, SWIR), multispectral imaging
• Acoustic — MEMS microphone arrays for sound classification, beamforming, acoustic event detection
• Radar — mmWave (60/77/79 GHz) for presence detection, vital signs monitoring, gesture recognition
• Custom sensors — Application-specific transducers designed to specification

Sensor Fusion Algorithms

Projects implement Extended Kalman Filters (EKF), Unscented Kalman Filters (UKF), particle filters, and neural network-based fusion running directly on the sensor MCU — eliminating the need for external processing and targeting <1 ms fusion latency.

Computer Vision at the Edge

Development Methodology

1. Data pipeline design — Sensor selection, data collection protocols, annotation strategy (CVAT, Label Studio)
2. Model development — Architecture search (NAS), training on representative data, quantization-aware training (QAT)
3. Optimization — INT8/INT4 quantization, structured pruning, knowledge distillation, ONNX graph optimization
4. Deployment — Model compilation for target hardware (TFLite, ONNX Runtime, TVM, ExecuTorch), runtime integration
5. Validation — On-device accuracy testing, latency profiling, power measurement, thermal characterization
6. Continuous improvement — OTA model updates, edge-cloud feedback loops for model retraining, A/B testing on-device

Cloud Data Processing & Visualization
