- Tactile sensors in general are used for measuring the physical parameters associated with contact between sensor and object. Tactile resonance sensors in particular are based on the principle of measuring the frequency shift, Deltaf, defined as the difference between a freely vibrating sensor resonance frequency and the resonance frequency measured when the sensor makes contact to an object. Deltaf is therefore related to the acoustic impedance of the object and can be used to characterize its material properties. In medicine, tactile resonance sensor systems have been developed for the detection of cancer, human ovum fertility, eye pressure and oedema. In 1992 a Japanese research group published a paper presenting a unique phase shift circuit to facilitate resonance measurements. In this review we summarize the current state-of-the-art of tactile resonance sensors in medicine based on the phase shift circuit and discuss the relevance of the measured parameters for clinical diagnosis. Future trends and applications enabled by this technology are also predicted.

- Due to the change in global demographics, a significant amount of research is being directed towards developing solutions to monitor and support the ageing as they perform activities of daily living. Research in this area is, however, being limited by the lack of shareable datasets available to support the development and evaluation of data driven activity recognition models. In our current work we have developed a suite of resources in an attempt to establish an openly available data repository where all datasets share a common format for the purposes of data storage. Within this paper the homeML Toolkit and the homeML Repository are presented. Results from a usability study of interactions with the toolkit, conducted by five computer science researchers are presented; the initial findings of which have been encouraging
