Within this research a smart textile based light sensor was developed and integrated into a technical demonstrator of a remote identification system. This sensor is based on polymeric optical fibers (POFs) which contain fluorescent dopants and allows a remote detection using an optical laser pulse for identification. A possible use case for this system is remote identification to avoid “friendly fire” incidents.The smart textile sensor can be integrated with a very low footprint in protective textiles or other equipment of the individual. Besides defense applications, the system could also be adopted for applications in which a safe, secure and fast remote identification is needed.

from the article: The demand for a wireless CO2 solution is ever increasing. One of the biggest problems with the majority of commercial available CO2 sensors is the high energy consumption which makes them unsuitable for battery operation. Possible candidates for CO2 sensing in a low power wireless application are very limited and show a problematic calibration process. This study focuses on one of those EMF candidates, which is a Ag4RbI5 based sensor. This EMF sensor is based on the potentiometric principle and consumes no energy. The EMF cell was studied in a chamber where humidity, temperature and CO2 level could be controlled. This study gives an detailed insight in the different drift properties of the potentiometric CO2 sensor and a method to amplify the sensors signal. Furthermore, a method to minimize the several types of drift is given. With this method the temperature drift can be decreased by a factor 10, making the sensor a possible candidate for a wireless CO2 sensor network.
OBJECTIVES: to test the effects of an intervention involving sensor monitoring-informed occupational therapy on top of a cognitive behavioural treatment (CBT)-based coaching therapy on daily functioning in older patients after hip fracture.DESIGN, SETTING AND PATIENTS: three-armed randomised stepped wedge trial in six skilled nursing facilities, with assessments at baseline (during admission) and after 1, 4 and 6 months (at home). Eligible participants were hip fracture patients ≥ 65 years old.INTERVENTIONS: patients received care as usual, CBT-based occupational therapy or CBT-based occupational therapy with sensor monitoring. Interventions comprised a weekly session during institutionalisation, followed by four home visits and four telephone consultations over three months.MAIN OUTCOMES AND MEASURES: the primary outcome was patient-reported daily functioning at 6 months, assessed with the Canadian Occupational Performance Measure.RESULTS: a total of 240 patients (mean[SD] age, 83.8[6.9] years were enrolled. At baseline, the mean Canadian Occupational Performance Measure scores (range 1-10) were 2.92 (SE 0.20) and 3.09 (SE 0.21) for the care as usual and CBT-based occupational therapy with sensor monitoring groups, respectively. At six months, these values were 6.42 (SE 0.47) and 7.59 (SE 0.50). The mean patient-reported daily functioning in the CBT-based occupational therapy with sensor monitoring group was larger than that in the care as usual group (difference 1.17 [95% CI (0.47-1.87) P = 0.001]. We found no significant differences in daily functioning between CBT-based occupational therapy and care as usual.CONCLUSIONS AND RELEVANCE: among older patients recovering from hip fracture, a rehabilitation programme of sensor monitoring-informed occupational therapy was more effective in improving patient-reported daily functioning at six months than to care as usual.TRIAL REGISTRATION: Dutch National Trial Register, NTR 5716.
