However, application of controlled sequences of olfactory stimuli within the setting of fMRI equipment is challenging since the associated limitations for non-magnetic and non-conducive materials. Here, we have developed and tested a simple, low-cost, open-source, stand-alone device to apply selectable controlled sequences of olfactory stimuli in subjects undergoing fMRI. The device consists of an Arduino-controlled unit containing a blower-based airflow generator and a multichannel air valves system, a set of long air conducting tubing, and bubbler-based odor sources. The device was first validated on the bench to characterize the range of achievable flows, ensuring that the device can be adapted to a variety of applications and fMRI settings. The effectiveness of device performance was subsequently assessed in female patients with sexual dysfunction using a fMRI protocol based on subjecting them to controlled sequences of olfactive stimuli with pheromone, phenethyl alcohol (a rose fragrance) or neutral clean air. Therefore, the device facilitates biomedical research and clinical assessment of the neural pathways modulated by the olfactory system.</div></div>","PeriodicalId":37503,"journal":{"name":"HardwareX","volume":"24 ","pages":"Article e00708"},"PeriodicalIF":2.1,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145320697","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its modular and ergonomic hardware with a printable enclosure, integrated pump driver, and labeled connectors lets non-experts assemble, calibrate, and service the unit quickly in the field.

The Recursive InterNetwork Architecture (RINA) presents a “clean slate” alternative, promising inherent solutions to these issues by redesigning networking from first principles. However, the practical exploration and adoption of RINA have been hampered by a lack of accessible, low-cost, and open-source hardware tailored for resource-constrained IoT environments. This paper introduces the RINAsense node, an open-source hardware platform designed to bridge this gap. The hardware is based on a low-power ESP32 microcontroller and integrates environmental sensors for temperature, humidity, and carbon monoxide, all managed by a custom RINAsense firmware designed specifically for embedded systems. The hardware was deployed and validated in an operational smart building testbed, demonstrating its capabilities as a reproducible scientific instrument. The validation confirmed the hardware’s successful operation, achieving low-latency communication with an average round-trip delay of 2.05 ms and a remarkable 82% reduction in energy consumption compared to non-optimized operation, a critical factor for battery-powered IoT devices. By providing a fully documented and replicable design, the RINAsense node lowers the barrier to entry for practical RINA research and experimentation, contributing directly to the open science and reproducibility goals of the research community.</div></div>","PeriodicalId":37503,"journal":{"name":"HardwareX","volume":"24 ","pages":"Article e00719"},"PeriodicalIF":2.1,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145466667","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
