Diagnosis: Nanosensors in Diagnosis and Medical Monitoring
Published in Harry F. Tibbals, Medical Nanotechnology and Nanomedicine, 2017
A number of advanced research projects are developing wearable sensors and smart fabric clothing to provide various types of continuous monitoring. Several such systems include communication capabilities to alert the wearer to reduce strenuous activity, for example, or to automatically alert healthcare givers of a serious change or trend in physiological signs. Some of the most sophisticated nano-engineered smart fabrics include combinations of hydrophobic and hydrophilic surfaces in channels to guide perspiration passively toward sensors without the need for an active pump mechanism. This biomimetic design is borrowed from the capabilities found in a number of insects with the ability to harvest water from the atmosphere.
The experience of using a hospital bed alternative at home among individuals with spinal cord injury: A case series

Data collection involved three components: questionnaires, a semi-structured interview, and pressure mapping. Most data collection occurred in the participants’ homes, with the exception of a portion of the pressure mapping which was done on the hospital campus. During the home visit, participants provided demographic information, injury characteristics, equipment information, and functional status (Table 1) via a brief questionnaire. They then participated in an audio-recorded interview that was guided by a set of discussion questions. Discussion topics included reasons for choosing an alternative adjustable bed system, experiences using the system, other pressure injury (PI) prevention activities, or related topics brought up by the interviewees (Table 2). Pressure mapping was then performed on the alternative adjustable bed system in the participant’s home. Within two weeks of the home visit, participants returned to the hospital campus to complete pressure mapping on a Drive Premium Guard Gel™ overlay on a hospital mattress meeting the standard of care for inpatient rehabilitation discharge recommendations. Pressure mapping was conducted using the BodiTrak Smart Fabric™ and FSA pressure mapping system (Vista Medical, Winnipeg, Manitoba, Canada). For both home and hospital-based pressure mapping, each participant transferred from his/her personal wheelchair to each bed surface using his/her daily typical transfer technique. Pressure mapping data were collected after 6 min in supine and after 6 min in side lying on each surface. Data collected included pressure gradient, coefficient of variation, sensing area, and average pressure at the sacrum and ischial tuberosities in supine and at the greater trochanter in side lying.
