This device is affordable ($118 USD for the first individual sampler with an incremental cost of $48 for the 10th sampler built) and collects data very similar to commercial pollen measurement devices (that cost $1300−$6000 per sampler). The design is portable, battery operated, programmable, and includes retracting sampling rods to prevent passive sampling between periods of active sampling and can include a rain shield to allow deployment in inclement weather. The main sampler is 135 × 75 × 93 mm and weighs 185 g, allowing for easy deployment on portable tripods at breathing height. As with other rotorod-style devices, active sampling time during normal pollen concentrations is limited to 1 h, but this sampling activity can be distributed across periods ranging up to several days; the timing of sampling is programmable through a simple and easily modifiable Arduino script. This validated sampler (r > 0.99 compared to a commercial rotorod-style device) is field tested and results have been published in several peer-reviewed publications. The Rotapollen Sampler is well suited for investigations of airborne pollen concentrations, and especially for sampling campaigns that simultaneously collect measurements in multiple locations, such as those that seek to understand spatial heterogeneity in airborne pollen concentrations.</div></div>","PeriodicalId":37503,"journal":{"name":"HardwareX","volume":"24 ","pages":"Article e00712"},"PeriodicalIF":2.1,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145416974","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}

For experiments in fluid dynamics, the ability to perform multivariate and multidimensional measurements is key to effectively studying complex thermofluidic phenomena. Generating multiple target views onto a single camera is a good way to reduce system costs by using fewer cameras. Currently, view splitting requires the purchase of expensive commercial lenses or the in-house design and fabrication of custom components, hindering the pace of research and development. Here, we provide an open-source design for a low-cost, general-purpose view splitter, providing up to four views per camera. All custom parts for the assembly are provided, which are designed for easy integration with standard optical components. Additional files are included for different view splitter orientations (designed for tomography) and the optional integration with spectral filtering. Characterization experiments were performed at multiple object distances to determine changes in image mapping quality, parallax angles, pixel density, and field-of-view (FOV). Validation is performed on a non-premixed methane/air flame, demonstrating the ability of the view splitter to perform simultaneous high-speed imaging and quantitative measurement in a practical system. This assembly has the potential to democratize access to advanced imaging capability and accelerate progress in the broader diagnostics community.</div></div>","PeriodicalId":37503,"journal":{"name":"HardwareX","volume":"24 ","pages":"Article e00723"},"PeriodicalIF":2.1,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145614678","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}

However, light-based bioprinting equipment can be costly and photo-sensitive materials difficult to optimize.

We provide instructions on how to optimize bioinks and printing conditions and explore novel bioresin additives utilizing cell-friendly photon absorption and radical scavenging strategies. As a proof of concept, we demonstrate the compatibility of our method for the ability of our printer to produce complex and perfusable architectures as well as successful cell printing with high post-printing viability.

Each of these phantoms is comprised of different silicone compositions representing different tissues, including a skin layer, healthy fat tissue, and cancerous tumour tissue.
