RTDT Laboratories

What RTDT Laboratories does

RTDT Laboratories AG is an ETH Zurich spin-off headquartered at Technopark Zurich that develops the Aerosense system — an ultra-thin (4mm), flexible, wireless sensor patch with integrated multi-modal sensing (aerodynamic pressure, acceleration, blade motion, vibration, strain, temperature) and autonomous solar-powered operation — for aero-structural monitoring of wind turbine blades. The hardware is paired with the Aerosense Intelligence Stack, a three-tier software platform delivering calibrated measurements, proprietary analytical insights on blade kinematics, aerodynamic coefficients, wind inflow, and structural integrity, and actionable recommendations for controller tuning, AEP boosting, lifetime extension, and risk management. The company serves two primary enterprise customer segments: wind turbine OEMs (including Siemens Gamesa and Suzlon) for design validation and aerodynamic upgrades, and wind farm operators/owners for control optimization and warranty load validation, with field-retrofit, factory-installation, blade-transportation, and wind-tunnel deployment modes.

RTDT operates a direct enterprise field-sales GTM motion, engaging wind turbine operators and OEMs through consultative, custom-engineering deployments with quote-based annual subscription pricing that bundles hardware (Aerosense sensor patches in 400×160×4mm and 160×160×4mm form factors) with software analytics. Revenue streams comprise hardware sales/leases and recurring subscription access to the analytics platform. The company has also expanded beyond wind energy into road infrastructure monitoring through a partnership with the Uttar Pradesh Expressways Industrial Development Authority (UPEIDA) on the Ganga Expressway (594 km), applying its sensor and AI technology to AI-driven road quality and traffic safety monitoring. Total disclosed funding stands at approximately USD 4.17 million, comprising a CHF 150,000 Venture Kick grant (October 2024) and a USD 4 million pre-seed round (June 2025) led by Swisscom Ventures with Rockstart, Backbone Ventures, and Kickfund. The company maintains advisory ties to ETH Zurich and OST Eastern Swiss University of Applied Sciences, and has received recognition including Forbes 30 Under 30 Europe (2025) and ZKB Pionierpreis Technopark 2026 finalist status.

Core offering

RTDT Laboratories AG sells the Aerosense system, a wireless, ultra-thin, solar-powered sensor patch that is field-retrofittable on wind turbine blades within minutes to capture aerodynamic pressure, acceleration, blade motion, vibration, strain, and temperature measurements. The hardware is bundled with the Aerosense Intelligence Stack, a subscription-based analytics platform that delivers calibrated measurements, proprietary analytical insights, and actionable recommendations for turbine design, control tuning, AEP boosting, lifetime extension, and risk management.

Product overview

RTDT Laboratories offers a unified hardware-software product centered on the Aerosense wireless sensor system. The Aerosense patch (available in two compact form factors: 400 × 160 × 4 mm and 160 × 160 × 4 mm) serves as the core sensing hardware, providing high-frequency, time-resolved measurements directly from wind turbine blades. This hardware is paired with the Aerosense Intelligence Stack, a software suite comprising three analytical modules: (1) Calibrated Measurements for high-frequency sensor data collection, (2) Analytical Insights leveraging proprietary algorithms for blade kinematics, aerodynamic coefficients, wind inflow conditions, and structural integrity, and (3) Actionable Recommendations covering controller tuning, AEP boosting, lifetime extension, and risk management. The system is designed for field retrofit, factory installation, blade transportation monitoring, and wind tunnel testing applications.

Functional benefit

Brands

• Aerosense: Wireless sensor patch product line for wind turbine blade monitoring, available in two compact versions (400 × 160 × 4 mm and 160 × 160 × 4 mm) providing aero-structural insights including aerodynamic pressure, acceleration, blade motion, vibration, strain, and temperature measurements.

Products and services

• Aerosense Aerosense is RTDT's integrated wind turbine structural health monitoring product, combining an ultra-thin, flexible, solar-powered wireless sensor patch (deployable on any blade model in minutes via removable tape) with the Aerosense Intelligence Stack—a three-tier software platform delivering Calibrated Measurements (high-frequency motion, vibration, strain, aerodynamic pressure), Analytical Insights (blade kinematics, aerodynamic pressure coefficients, wind inflow conditions, structural integrity), and Actionable Recommendations (controller tuning, AEP boosting, lifetime extension, aerodynamic upgrades, design modifications, CAPEX reduction, insurance/risk management). It targets wind turbine operators, OEMs (Siemens Gamesa, Suzlon), and government infrastructure authorities, with applications including field retrofit, factory installation, blade transportation monitoring, and wind tunnel testing.

Quantifiable outcome

• Turbines currently operate below their full potential because of the lack of site-specific aero-structural data at scale — RTDT's solution addresses this fundamental efficiency gap.
