In-Memory Sensing and Computing

Sandro Carrara


Institute of Electrical and Micro Engineering, Engineering Faculty

EPFL, École Polytechnique Fédérale de Lausanne



The concept of in-Memory Computing is nowadays a well-established principle. Instead of separating the processing device by the memory units, as usually done in traditional von Neumann architectures, it proposes new architectures based on memory devices providing simultaneous computing. Indeed, this keynote speech proposes the new concept of in-Memory Sensing and Computing as a disruptive novel approach in edge-computing. This novel concept is here proposed as based on the fusion of three architectural functions: sensing, computing and memorizing. This novel concept is proposed by using a simple architecture based on a single-kind of devices simultaneously providing these three functions: the memristors. The proposed novel approach also provides a breakthrough in cancer diagnostics. If fact, the concept is here demonstrated by showing a well-known case in oncology: the estimation of the risk of prostate cancer based on the measure of Prostate Specific Antigen (PSA) and its Membrane isoform (PSMA). So, this keynote discusses the first-ever-reported direct computation of the cancer risk on cancer markers detected with memristive biosensors simultaneously with the computation and data storing.  Memristive biosensors are quite a novelty emerged in literature with first publications starting from 2011. These new kind of devices are of interest for many reasons but especially for their excellent Limit-of-Detection, which is down to the attomolar-ranges in cancer markers detection. They are often fabricated on silicon nanowires and manufactured with standard lithographic processes.  This means the whole architecture may be CMOS-based and the biosensors themselves can be physically microfabricated onto the same dye. Therefore, this keynote talk opens to an important new area of research and development: the possibility to build innovative circuits and systems providing simultaneous sensing, computing, and storing for true lab-on-a-chip applications.

SOCs Powering Intelligent Neuro-Modulation Biomedical Systems - Innovations and Challenges

Chung-Yu Wu

Emeritus Chair Professor

Institute of Electronics, National Yang Ming Chiao Tung University



Closed-loop neuro-modulation has been proven as an adaptive and optimal treatment for a range of intractable neurological disorders or diseases like drug-resistant epilepsy, Parkinson’s diseases, chronic pain, dementia, etc. The biomedical systems realizing implantable closed-loop neuro-modulation have become a rapid growing and challenging research frontier. Enabled by CMOS IC technologies, the core circuits of implantable closed-loop neuro-modulation systems can be integrated together to form a SoC (System-on-Chip), instead of discrete components as in nowadays commercial products. Greatly powered by SoCs, the SoC-inside implantable neuro-modulation systems have the advantages of small size, low power dissipation, high speed, and high accuracy. This makes them more effective and efficient in closed-loop neuro-modulation.

Epilepsy is defined as a tendency to have recurrent seizures. Epileptic seizures are caused by a sudden burst of excess electrical activity in the brain. As the fourth most common neurological disorder, 70 million people have epilepsy worldwide and about 30% of them are intractable. It is quite feasible to use SoC-inside implantable closed-loop neuro-modulation systems on these patients to suppress epileptic seizures through electrical stimulation. An implantable CMOS closed-loop neuro-modulation system for epilepsy control has been developed since 2008. It consists of an extraocular chip and an intraocular SoC with rechargeable battery. Both are coupled by a pair of coils operated at 13.56 MHz for wireless power and bilateral data telemetry. The implantable SoC consists of ECoG (Electrocorticography) acquisition unit, biphasic CCS (Constant Current Stimulation) stimulators, BSP (Bio-signal Processor), power management unit, battery charger, and wireless telemetry circuits whereas the extraocular chip contains power amplifier, charging control circuits, and wireless telemetry circuits. The SoC-inside system detects patient’s ECoG and automatically generates stimulus current pulses to suppress epileptic seizures. The design and measurement results of innovative SoC design and whole closed-loop neuro-modulation system will be presented. The results of initial clinical trial will be described.

The on-going research on closed-loop DBS (Deep Brain Stimulation) SoC for Parkinson’s diseases will be highlighted. Finally, design challenges on circuits and systems for implantable neuro-modulation will be addressed. New discovery on dementia paving the road of neuro-modulation treatment will also discussed as a future perspective.

Data Harmonization: An Imaging-driven Omics Database / Repository for Retrospective Understanding of COPD and Planning for Future Care

Andrew Laine

Percy K. and Vida L. W. Hudson Professor of Biomedical Engineering and Professor of Radiology (Physics)

Consistent imaging protocols will require normalization / harmonization of data sourced from multiple platforms, hospitals and vendors. AI has shown a remarkable ability to generalize and group / tease out patterns from high-dimensional data. Machine / deep learning algorithms should rely on mix-omics integration of imaging and physiological measures. There is an urgent need for new models of multi-modal transfer learning (e.g., understanding lung and heart functional interactions), and incremental learning as cohorts grow at an ever-faster face, combining data from states/countries.
We are in the process developing harmonization methods that are applied to COPD patient imaging data. This phenotyping could lead to a better retrospective understanding of COPD disease pathways and prepare for future management of pulmonary-derived chronic pathologies. In addition, there are significant new chronic pathologies expected in COVID survivors (cardiomyopathy, pulmonary aspergillosis, hemoglobin / iron deficiencies) in the longer term, which will be challenging to treat and / or recognize. The harmonized baseline data during acute phases of disease would help tremendously in our ability to understand the implications of these pathologies.
The proposed harmonization platform would include normalization across vendors, sites, possible variations in protocols and patient size. We describe AI based harmonization methods to leverage a large number of baseline scans from existing and ongoing studies for density measures, texture and later airway topology. During this initial phase, the Columbia cohort would harmonize 2,500 subjects in total, sampling in proportion five distinct cohorts. In the long term we aspire to develop data sharing tools, with possible partnerships for long term / global infrastructure and computing, integrate expertise in multiple imaging modalities, lead an open AI approach to model, predict and understand stages of pulmonary disease including COPD.
