Wireless system-on-chip devices are emerging as the most promising solution for future wireless sensing with applications in medical implants and the Internet of Things (IoT). On one side, energy extraction from ambient sources facilitates permanent powering techniques required for long-term operation. On the other side, the high integration capability of commercial CMOS technology opens the opportunity for high-resolution sensing and data communication with a compact form-factor. In this dissertation, My research builds a foundation for joint wireless power delivery, low-power sensing, and wireless communication in such highly integrated systems yielding a paradigm shift in the design and development of future ubiquitous low-power wireless systems. This thesis presents the design, implementation, and experimental evaluation of integrated wirelessly powered solutions for next-generation medical implants and IoT devices. To this end, First, I leverage the high integration capabilities of CMOS technology and try to develop integrated systems for power delivery, environmental sensing, and wireless data communication. The small power budget available for an integrated solution severely limits its functionality and operating range. Hence, individual wirelessly powered solutions may not be able to satisfy the application requirements of future medical implants and IoT devices. To address this problem, I leverage another important feature of a commercial CMOS technology that is the low fabrication cost. I show how complex tasks such as localization and be realized using a swarm of millimeter-sized integrated chips. In this dissertation, I introduce the challenges of wireless power transmission to fully integrated systems on CMOS technology and present two types of RF power receiver systems for near-field and far-field electromagnetic region. I propose a comprehensive optimization algorithm for maximizing the power transfer efficiency and choosing the optimum frequency for wireless power transmission. Next, I present the world's most power-efficient wireless transceiver with an integrated wireless power delivery system. I demonstrate a fully on-chip operation and utilize two sets of loop and dipole antenna for wireless power delivery and data communication, respectively. I will explain how we achieve a 150 Mbps uplink communication data rate under a stringent power budget by introducing a power management technique. I will then, discuss the opportunities offered by this platform to enhance next-generation IoT and medical devices. In particular, we tackle the limited operating range by forming a synchronized distributed sensor network built from fully on-chip integrated systems. Also, we address the power scarcity challenges in biomedical/environmental sensing by adopting extensive low-power design techniques. This interdisciplinary research direction incorporates advancements such as applied physics, machine learning, healthcare, and wireless networking.

Neural interfacing is a promising technology for effectively treating a multitude of challenging clinical conditions. Recent research has demonstrated that some tetraplegic patients can control robotic limbs using a brain-computer interface (BCI), signifying the beginning of an era wherein many forms of paralysis may be treatable with a neuro-prosthesis. However, the current state of the art is bulky, tethered, and impractical for applications outside a clinical lab setting. Moreover, current wireless communication approaches for brain computer interfaces (BCI) do not meet the necessary specifications for power, size, and bandwidth. In contrast, we developed fully integrated BCIs equipped with high data-rate and low power miniaturized wireless backscatter communication systems to enable the development of autonomous brain-controlled prosthetics. First, we proposed a wireless [mu]-Power, low-noise frequency mixing approach for extending the passband frequency response of existing neural interfaces. We demonstrated the translation of a pre-recorded mouse electrocorticogram from a frequency range of 0.5 Hz to 100 Hz up to an intermediate frequency (IF) of 407 Hz, thus enabling the use of an existing integrated circuit (IC) for electrocorticography (ECoG), despite its low-frequency cutoff of 12 Hz. Subsequently, we presented a dual-band implantable BCI that integrates 47%-efficient high frequency (HF) wireless power delivery into a 5 Mb/s ultra-high frequency (UHF) backscatter communication. The implant system supports ten neural channels sampled at 26.10 kHz and four electromyography (EMG) channels sampled at 1.628 kHz and can communicate with a custom software-defined-radio-based external system with a packet error ratio (PER) that is better than 0.19%~at an implant depth of up to 3 cm. Finally, in order to enable neural plasticity experiments inside the home cages of freely behaving animals, we developed a 25 Mbps backscatter-based data uplink for Neurochip 3 using a differential quadrature phase shift keying (DQPSK) constellation. We statically collected 104 packets from 126 locations, and the system exhibited effectively 0% (PER) for all but two of the surveyed sites despite the reverberant cavity effects of the animal cage that critically impair the communication channel.

This work addresses challenges in power delivery, efficient computation and communication to power-constrained wearable and implantable devices. We are surrounded today by over 25 billion smart devices, and this number is constantly increasing. Owing to the shrinking CMOS technology, some of these devices are so small that they can even be worn on the human body or implanted inside it. The sheer number of devices and their drastic minia- turization and integration into the human body posit two major challenges. First, how do we communicate with these numerous small devices? Second, how do we deliver power to them? The wearable or implantable nature of these smart devices only exacerbates these challenges. Since these devices are designed to be worn or implanted, they must be small, comfortable and, most importantly, safe to use. They must be small so that they are dis- crete when worn or can be implanted easily. They must be comfortable so that people can use them for extended periods of time for physiological monitoring, without the devices in- terfering with their normal lifestyle. Finally, they must not cause discomfort by overheating and operate at low power consumption so that they are safe to use. Traditionally, cables were used to power or communicate. However, with the proliferation of smart devices, tethering to communicate with or to recharge them is no longer a practical solution. Bluetooth technology allows some degree of wireless communication with smart devices, but it is a power-hungry technology and thus unsuited for implanted devices. Hence there is a need for reliable communication of data at low power levels. Batteries are currently the most prevalent option for power delivery, but are a less-than-ideal solution. While progress in CMOS technology has reduced size and power consumption of smart devices, the batteries used to power them are still large. With higher energy requirements, larger these batteries become. Even when rechargeable, these batteries have a diminishing eciency over their lifetime of about two to three years. Hence, they are not the best option for powering these billions of devices, especially when they are implanted in the body and need surgery for replacement. One of the solutions to make these devices untethered and battery free is to use wireless power transfer and low-power wireless communication. However, these smart devices used in diverse application have vastly dierent power requirements and communication data rates. Hence, it becomes dicult to standardize ways to wirelessly power and communicate with them. The wireless solutions presented here are applied to two different applications, one wearable and the other implantable, demonstrating the ability to serve diverse requirements. The first application includes a wearable sensing platform that operates with ultra-low power consumption to perform analog sensing of physiological signals and use backscatter communication, which is an ultra-low power communication method, to transmit sensed data. The total power consumption for sensing and communicating data to an external base station is as low as 35 [micro]W to 160 [micro]W. This modular wireless platform is battery- free and can be made in the form of an adhesive bandaid that can sense physiological parameters like heart rate, breathing rate and sense sounds to monitor health conditions. Thus it enables simple, continuous and seamless monitoring of health parameters while a person goes about their everyday tasks. The second application is an implantable platform that can record neural signals from the brain and process them locally to identify events in the signals that can trigger neural stimulations. The requirements for this implantable device are far more complex than the simple wearable application. The implants operate with several 100 mW of power consumption and need several Mbps data rates to transmit the recorded and processed data out to the user. To address the high power and high data rate requirements, this work presents a novel dual-band approach that supports wireless power delivery at high frequency (HF) and backscatter communication at ultra-high frequency (UHF). At the smart implantable device, the dual-band wireless system harvests energy from HF wireless signals while simultaneously communicating data using UHF backscatter. To localize the implant and deliver power to it, a novel low-overhead echolocation method is presented in this work. This method uses reflected parameters on a phased array of wireless power transmitters to locate the wireless device and deliver focussed power to it. The implantable platform is intended for use in two different application domains. First, in neural engineering research where neural interface devices are used to understand, record and map the brain function and to leverage them and develop brain-controlled technology like prosthetic limbs. Second, for treatment and rehabilitation of people suffering from spinal cord injury and chronic neural disorders. An implantable brain-computer-spinal interface (BCSI) is presented in this work, that records neural signals and processes them locally to extract intent. The decoded action intention can be used to trigger stimulation in the spinal cord to reanimate the paralyzed limb and perform the action. In addition, this device is developed as a low-power FPGA-based platform so that it is reconfigurable to enable research in closed-loop algorithms to understand and treat several other neural disorders. We expect that such wireless biomedical sensing can provide a better understanding of physiological parameters and enable treatment for chronic disorders.
