The advent of the Internet of Things (IoT) has led to an increased demand for security and real-time guarantees in distributed embeddedsystems comprising the IoT. Securing edge-based systems with limited resources can be especially problematic due to challenges in adapting traditional network security protocols. In this work, we introduce two methods to provide security guarantees in resource-constrained devices-based ioT systems. As a case study, we propose an integration of Secure Swarm Toolkit (Sst), an open-source framework for IoT security, with Lingua Franca (LF), a software platform for concurrent and time-sensitive applications. We report preliminary results on our work-in-progress implementation and experiments, followed by concrete future research plans.

The rapid growth in wireless embeddedsystems is threatened by the challenges associated with programming and deploying them. In addition, there is also the complexity inherent in analyzing of the sensor data. Notably, these tasks require high levels of end-user expertise. In this way, an entry barrier is introduced to deploying wireless embeddedsystems. In this work, we introduce Otter, an end-to-end system designed to simplify these tasks by leveraging the emergent properties of large language models. We demonstrate that Otter allows commodity embedded platforms to capture sensor data, such as light and vibration sensors, which can then be used to identify hand gestures in a near real-time manner. This is all while being prompted using natural language prompts by the end-user. Otter is the first system of its kind and has the potential to facilitate wireless embeddedsystems proliferation significantly.

Voice is a convenient and popular way to interact with our digital world. Besides translating speech to text, it is also possible to identify speakers based on their voice profile. To date, speaker identification has predominantly been limited to high-performance computational platforms owing to the intricate nature of the underlying algorithms. In this work, we demonstrate that it is possible to reduce model complexity by the required factor of similar to 10, such that speaker identification can be made feasible for embedded devices with limited resources. We further describe and discuss novel use cases, such as voice-based presence detection and authentication, that become feasible on these class of devices.

We investigated the possibility of using the output voltage of magnetic resonant coupled coils to realize a distance sensing method that can be applied even when the distance between coils is long. We changed the distance between PCB boards with 1 cm coils and measured the output voltage induced in one coil when an AC voltage of the resonant frequency is input to the other coil. As a result, a correlation was confirmed between the distance between the coils and the value of the output voltage. We found that the distance between the coils can be estimated from the output voltage even when that distance is more than five times the coil diameter. This method enables distance sensing between objects simply by placing a coil on the object. This allows for the sensing of positional relationships between components used in deformable user interfaces.

In this paper, a displacement sensing method utilizing the bit-error characteristics in inter-chip wireless bus is presented. A non-contact displacement sensor is highly demanded in many engineering fields, and its miniaturization contributes to the expansion of further application areas and simplifies implementation. Inter-chip wireless bus is a short-range wireless communication technology that uses a small coupler, and its bit-error characteristics change according to the relative position between couplers. Additionally, the bit-error rate in inter-chip wireless bus can be obtained solely by digital processing through a tiny microcontroller. Therefore, a tiny digital displacement sensor, integrating a small coupler, wireless transceiver circuits, and a microcontroller, can be realized. The principle of proposed sensing method is verified using simulations, and a 1 mm x 1 mm CMOS LSI test chip is designed and fabricated using 180-nm CMOS technology.

Radar sensors have recently been explored in the industrial and consumer Internet of Things (IoT). However, such applications often require self-sustainable or untethered operations, which are at odds with the high power consumption of radar. This paper proposes NEURORADAR, a neuromorphic radar sensor, to achieve low-power wireless sensing. NEURORADAR jointly optimizes the analog hardware and the computation model, in order to mimic the highly efficient biological sensing and neural processing system. NEURORADAR features a highly simplified radar front end, which eliminates the power-hungry components in conventional radars. It directly "encodes" ambient motion into spiking signals, which can be processed using spiking neural networks running on energy-efficient neuromorphic computing platforms. We have prototyped NEURORADAR and evaluated its performance in two use cases: gesture sensing and localization. Our experiments demonstrate that NEURORADAR can achieve high sensing accuracy, at orders of magnitude lower power consumption compared with traditional radar.
