These individuals may have a satisfactory recovery by applying functional electrical stimulation that enables the artificial restoration of grasping after a muscular conditioning period. This paper presents the STIMGRASP, a home-based functional electrical stimulator to be used as an assistive technology for users with tetraplegia or hemiplegia. The STIMGRASP is a microcontrolled stimulator with eight multiplexed and independent symmetric biphasic constant current output channels with USB and Bluetooth communication. The system generates pulses with frequency, width, and maximum amplitude set at 20 Hz, 300 \u00b5s\/phase, and 40 mA (load of 1 k\u03a9), respectively. It is powered by a rechargeable lithium-ion battery of 3100 mAh, allowing more than 10 h of continuous use. The development of this system focused on portability, usability, and wearability, resulting in portable hardware with user-friendly mobile app control and an orthosis with electrodes, allowing the user to carry out muscle activation sequences for four grasp modes to use for achieving daily activities.<\/jats:p>","DOI":"10.3390\/s23010010","type":"journal-article","created":{"date-parts":[[2022,12,20]],"date-time":"2022-12-20T03:56:08Z","timestamp":1671508568000},"page":"10","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["STIMGRASP: A Home-Based Functional Electrical Stimulator for Grasp Restoration in Daily Activities"],"prefix":"10.3390","volume":"23","author":[{"given":"Renato G.","family":"Barelli","sequence":"first","affiliation":[{"name":"Electrical Engineering Department, Centro Universit\u00e1rio FEI, S\u00e3o Bernardo do Campo 09850-901, SP, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1695-1815","authenticated-orcid":false,"given":"Valter F.","family":"Avelino","sequence":"additional","affiliation":[{"name":"Electrical Engineering Department, Centro Universit\u00e1rio FEI, S\u00e3o Bernardo do Campo 09850-901, SP, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2751-0014","authenticated-orcid":false,"given":"Maria Claudia F.","family":"Castro","sequence":"additional","affiliation":[{"name":"Electrical Engineering Department, Centro Universit\u00e1rio FEI, S\u00e3o Bernardo do Campo 09850-901, SP, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,20]]},"reference":[{"key":"ref_1","unstructured":"World Health Organization (WHO) (2006).
