Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
A non-invasive piezoelectric-based sheet sensor is utilised for the deliberate measurement of heartbeat rate and blood pressure. It may consist of a single sheet to capture various temporal signals or it can be formed as an array of small piezoelectric sensors to capture the temporal and spatial cardiac signals over the chest to give an added spatial granularity on top of the localised temporal signal. The mechanical activity of the heart will cause the piezoelectric sheet to deform, and thus produce a voltage signal. To count the heartbeat rate, a mechanical model has been developed using the corresponding electric waveform; a compression ratio is defined due to the delay as a result of the physical coupling mechanism. Validation of the obtained results has been performed using conventional techniques and apparatus. The quantitative assessment shows low errors when compared with other conventional meters.
