The Positive and Negative Impact of an Intergenerational Digital Technology Education Programme on Younger People's Perceptions of Older Adults

In order to meet the technological needs of older adults, and ensure digital inclusion, it is important for digital technology designers to accurately assess and understand older adults’ needs and requirements, free from the influence of societal assumptions of their capabilities. This study evaluated the impact of an intergenerational digital technology education programme on younger adults’ stereotypes of older people. Using an experimental design, results show that compared to a control group, students taking part in the programme subsequently rated older adults as more friendly but less competent. Practical implications for developing intergenerational education programmes are discussed

Transport of sub-nanoliter volume droplets by electrowetting-on-dielectrics in air

Electrowetting-on-dielectrics (EWOD) is a commonly used technique for manipulation of droplets in digital microfluidic systems. Typical droplet volumes range from several microliters to milliliters, and when downscaling is desired the system is usually filled with oil. Here, we demonstrate actuation of sub-nanoliter droplets in air

Wearable sweat sensing for prolonged, semicontinuous, and nonobtrusive health monitoring

Together with the upcoming market for wearable consumer technologies, noninvasive and continuous health monitoring has become a new trend in the healthcare landscape. In recent years, significant research has been targeted toward the development of wearable sensing devices for monitoring biomarker levels in nonobtrusively accessible biofluids such as tears, urine, saliva, and sweat. Sweat could be an ideal candidate for prolonged, semicontinuous, and nonobtrusive health monitoring because sweat is a continuously accessible biofluid containing physiologically and metabolically rich information. However, challenges still remain toward commercialized wearable sweat‐sensing devices, and the correlation between biomarker concentrations in sweat with health conditions still seems to be not fully understood. This review article aims to display the full scope of sweat sensing for health monitoring, starting from the fundamentals of human sweat, via modeling of the sweat gland physiology toward wearable sweat‐sensing devices in research and commercialization efforts. Finally, the challenges of sweat sensing that still have to be overcome toward the utilization of sweat sensing in the conventional healthcare settings are discussed

Microelectrode Arrays for Simultaneous Electrophysiology and Advanced Optical Microscopy

Advanced optical imaging techniques address important biological questions in neuroscience, where structures such as synapses are below the resolution limit of a conventional microscope. At the same time, microelectrode arrays (MEAs) are indispensable in understanding the language of neurons. Here, the authors show transparent MEAs capable of recording action potentials from neurons and compatible with advanced microscopy. The electrodes are made of the conducting polymer poly(3,4-ethylenedioxythiophene) doped with polystyrene sulfonate (PEDOT:PSS) and are patterned by optical lithography, ensuring scalable fabrication with good control over device parameters. A thickness of 380 nm ensures low enough impedance and >75% transparency throughout the visible part of the spectrum making them suitable for artefact-free recording in the presence of laser illumination. Using primary neuronal cells, the arrays record single units from multiple nearby sources with a signal-to-noise ratio of 7.7 (17.7 dB). Additionally, it is possible to perform calcium (Ca2+) imaging, a measure of neuronal activity, using the novel transparent electrodes. Different biomarkers are imaged through the electrodes using conventional and super-resolution microscopy (SRM), showing no qualitative differences compared to glass substrates. These transparent MEAs pave the way for harnessing the synergy between the superior temporal resolution of electrophysiology and the selectivity and high spatial resolution of optical imaging

How to guide the use of technology for ageing-in-place:An evidence-based educational module

Technology is suggested to support ageing-in-place. For careand technology professionals working with older persons it is important to know how to facilitate the use of technology by older persons. This paper presents the translation of the results of a field study into multilevel and multidisciplinary educational material. During home visits, community-dwelling seniors were interviewed regarding reasons for their level of technology use. All types of technology that could support activities of daily living, were included. Resulting themes formed the basis of the development of personas and scripts for education. Next, lecturers from vocational and higher technical and care education developed an evidence-based educational module from the perspective of professional service provision. 53 older adults were interviewed. The level of technology use is influenced by six themes: challenges in the domain of independent living; behavioural options; personal thoughts on technology use; influence of the social network; influence of organisations; and the role of the physical environment. Four personas were developed, one of which was featured into a film, with twelve separate scenes. For each scene, lessons were developed that consisted of specific questions (first level), in-depth questions (second level) and suggestions for classes (for lecturers). Three personas were translated into case histories. Older adults’ perceptions and use of technology are embedded in their personal, social, and physical context. To improve successful technology use to support ageing-in-place, professionals from the domain of care and technology can be trained to be aware of these factors
