Figure 1 & 2: Professor Noushin Nasiri, inventor and scientific lead behind the 3D ZnO nanostructure Nanosensor platform, specialising in nanomaterials, miniaturised sensing and wearable electronics.

Professor Nasiri’s work on 3D ZnO film-based optical sensing was supported by Cancer Institute NSW Fellowship, 2023–2025 and is the winner of the 2025 Australian Museum Eureka Prize for Innovative Use of Technology, and a recipient of major competitive fellowships including the 2024 ARC Industry Fellowship and the 2022 L’Oréal–UNESCO For Women in Science Fellowship.

The underlying Technology is the subject of a patent application titled Capillary force induced nanowelding in metal oxide 3D nanostructures (PCT/AU2024/050143), covering the nanostructured zinc oxide architecture and related methods.

Nanotechnology is increasingly central to next-generation sensing because nanoscale architectures can deliver higher performance in smaller, lower-power devices. In this case, the 3D ZnO nanostructure design is intended to enhance sensitivity and signal quality while supporting miniaturised form factors suitable for embedded IoT nodes and wearables.

For Simble, this provides a pathway to differentiated Nanosensor capability that can be progressively integrated into SimbleSense deployments and CarbonView reporting over time.

WHY ADVANCED NANOSENSOR TECHNOLOGY MATTERS

Conventional environmental and optical sensing hardware can face challenges such as limited sensitivity, interference, elevated background signal (reducing signal-to-noise performance), and relatively larger size and power requirements.

The Nanosensor Technology, based on a semi-conductive 3D zinc oxide nanostructure architecture, is designed to address these limitations by enabling:

• High sensitivity for environmental and optical sensing applications;

• Very small form factor , with a pathway to sub-millimetre scale devices;

• Low power consumption suitable for battery-powered and embedded IoT deployments; and

• Integration into existing devices , including industrial equipment, wearables and connected electronics.

In a regulatory environment increasingly focused on WHS, environmental performance, sterilisation verification and ESG reporting, access to accurate, real-time sensing data is a natural extension of Simble’s existing capabilities in energy analytics and carbon reporting— enabling SimbleSense and CarbonView to deliver a more complete, auditable view of operational conditions alongside energy and emissions outcomes.

Across these sectors, Nanosensors act as the “data layer” that turns devices into always-on monitoring systems. Their compact form factor and low-power operation enable seamless embedding into wearables and e-skin, integration into industrial equipment and building systems, and deployment into robotics and emerging micro-/nanorobotic platforms.

E-skin sensing is a clear extension of this capability. E-skin systems use flexible, stretchable films embedded with dense micro-sensor arrays to create a skin-like sensing layer that can measure touch and contact dynamics, such as pressure, vibration and temperature, across large surface areas. When applied to robotic grippers and prosthetics, these e-skin sensor layers can improve safe human–robot interaction and enable more precise handling of delicate objects, with relevance across medical robotics and disaster-response use cases. In many designs, the e-skin is manufactured using polymer substrates and printed sensor networks, allowing devices to conform to complex shapes and respond in real time to physical contact.

As these sensors generate continuous, high-resolution environmental and operational data, they can be paired with SimbleSense and CarbonView to support real-time alerts, trend analytics and auditable reporting for customers.
