“…A 116 nW wake-up radio has recently been demonstrated, complete with crystal reference, interference compensation, and baseband processing, such that a selectable 31-bit code is required to toggle a wake-up signal [16]. The front-end operates over a broad frequency range, tuned by an off-chip band-select filter and matching network.…”

| This article provides the latest advances from the NSF Advanced Self-powered Systems of Integrated sensors and Technologies (ASSIST) center. The work in the center addresses the key challenges in wearable health and environmental systems by exploring technologies that enable ultra-long battery lifetime, user comfort and wearability, robust medically validated sensor data with value added from multimodal sensing, and access to open architecture data streams. The vison of the ASSIST center is to use nanotechnology to build miniature, selfpowered, wearable, and wireless sensing devices that can enable monitoring of personal health and personal environmental exposure and enable correlation of multimodal sensors. These devices can empower patients and doctors to transition from managing illness to managing wellness and create a paradigm shift in improving healthcare outcomes. This article presents the latest advances in high-efficiency nanostructured energy harvesters and storage capacitors, new sensing modalities that consume less power, low power computation, and communication strategies, and novel flexible materials that provide form, function, and comfort. These technologies span a spatial scale ranging from underlying materials at the nanoscale to body worn structures, and the challenge is to integrate them into a unified device designed to revolutionize wearable health applications.

“…They all have a data rate above 100 kb/s with a sensitivity varying over a broad range. Two designs [22,35] are using envelope detectors followed by purely analog non-coherent correlators and, thus, are able to reach very low power consumption values. Five concepts are using duty cycling [18,25,29,30,46], where [18,29,30,46] are duty cycling even within a bit having an ON time in the range of only .…”

In wireless sensor networks (Wsns) energy efficiency and communication reliability are often conflicting requirements. additionally, some application areas such as industrial automation or infrastructure monitoring impose strict latency bounds.Low-power receivers ( mW 1 1 power consumption) together with adapted mac protocols have the potential to meet these diverse requirements. We present an overview of state-of-the-art low-power receivers and relate their characteristics to requirements for different application areas. We compare low-power receivers to duty-cycled transceivers and present applications depending on them. For this, we use power consumption, sensitivity, and data rate as key performance figures for low-power receivers. Based on the characteristics of the applications we derive guidelines for using low-power receivers instead of duty-cycled transceivers. project "AETERNITAS".Johannes Blanckenstein works on communication protocols in the general field of wireless sensor networks and especially on protocols and applications for low-power wake-up receivers. He writes his doctoral thesis at University Paderborn in the computer networks group of Holger Karl. At the same time he works at Airbus Group Innovations in the field of WSN applications for aeronautics.

An area-ef cient 60-GHz wake-up receiver (WuRx) using recon guration techniques of multistage low-noise ampli ers (LNAs) is presented. The gain stages of the 60-GHz LNA are reused as the envelope detectors for the wake-up receiver. Therefore, the bulky components such as extra switches between the wake-up receiver and the LNA, additional antennas, and excess input matching network can be removed in the design of the wakeup receiver. Furthermore, due to the recon gurability of the LNA, the wake-up receiver can work in sensitivity-boost mode by using several LNA gain stages as a pre-ampli er. The wake-up receiver is fabricated in a 65-nm CMOS process occupying a core area of 0.015 mm 2 (excluding the LNA). The WuRx achieves the sensitivity of −46 dBm and −60 dBm with a power consumption of 64 μW and 12.7 mW, respectively.
