People in their daily life experience varying emotional states, some of which are negative and which can lead to decreased attention, decreased productivity and ultimately, reduced quality of life. Therefore, having a solution that continuously monitors the physiological signals of the person and assesses his or her emotional well-being could be a very valuable tool. This paper aims to review existing physiological and motional monitoring devices, highlight their features and compare their sensing capabilities. Such technology would be particularly useful for certain populations who experience rapidly changing emotional states such as people with autism spectrum disorder and people with intellectual disabilities. Wearable sensing devices present a potential solution that can support and complement existing behavioral interventions. This paper presents a review of existing and emerging products in the market. It reviews the literature on state-of-the-art prototypes and analyzes their usefulness, clinical validity, and discusses clinical perspectives. A small number of products offer reliable physiological internal state monitoring and may be suitable for people with Autism Spectrum Disorder (ASD). It is likely that more promising solutions will be available in the near future. Therefore, caregivers should be careful in their selection of devices that meet the care-receiver\u2019s personal needs and have strong research support for reliability and validity.<\/jats:p>","DOI":"10.3390\/s18124271","type":"journal-article","created":{"date-parts":[[2018,12,4]],"date-time":"2018-12-04T11:56:18Z","timestamp":1543924578000},"page":"4271","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":125,"title":["A Review of Wearable Solutions for Physiological and Emotional Monitoring for Use by People with Autism Spectrum Disorder and Their Caregivers"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9147-4580","authenticated-orcid":false,"given":"Mohammed","family":"Taj-Eldin","sequence":"first","affiliation":[{"name":"Tyndall National Institute, University College Cork, T12 R5CP Cork, Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4940-1377","authenticated-orcid":false,"given":"Christian","family":"Ryan","sequence":"additional","affiliation":[{"name":"School of Applied Psychology, University College Cork, T12 R5CP Cork, Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brendan","family":"O\u2019Flynn","sequence":"additional","affiliation":[{"name":"Tyndall National Institute, University College Cork, T12 R5CP Cork, Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul","family":"Galvin","sequence":"additional","affiliation":[{"name":"Tyndall National Institute, University College Cork, T12 R5CP Cork, Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2018,12,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2283","DOI":"10.1007\/s10803-015-2361-5","article-title":"Co-occurring psychiatric disorders in preschool and elementary school-aged children with autism spectrum disorder","volume":"45","author":"Salazar","year":"2015","journal-title":"J.
