C.O.M.P.A.C.T. Charging Of Mobile Phones Activated thru Conducting Thermoelectricity

Abstract

Mobile phone charging any time in any place," that is the goal of C.O.M.P.A.C.T., a thermo-electric conducting device that can directly convert heat into electricity. It applies the Peltier and Seebeck Effect on a thermoelectric cooler Peltier plate wherein a temperature gradient (hot on one side, cold on the other) can produce electricity. Within this, the researchers tested the device's effectiveness, charging time, and feasibility as a source of electricity by using five subject phones (brand includes Cherry Mobile, Samsung, Oppo, Huawei, and Blackberry). Two data gathering methods were utilized-first was an observation of C.O.M.P.A.C.T.'s charging the subject phones with their charging time compared to phone charging using their own original charger plugged in a two-hole socket (control set-up), considering the source of heat and its distance (lit medium candle, 12 inches away), phone condition (0% mAh, 50% brightness, disabled Data, WIFI, etc.), and number of TEC plates used (2) was constant; second was a questionnaire for rating in terms of scopes. Observation shows that C.O.M.P.A.C.T. can fully charge the subject phones from 0% to 100% for 3 hours and 6 minutes on average, slower than the control set-up by 20 minutes. Meanwhile, 127 respondents reacted strongly agree (mean of 3.59 in 4-rating scale) for being effective, time-efficient, and feasible as a source of electricity. Hence, C.O.M.P.A.C.T. was an effective device to fully charge different phones with 3 hours and 6-minute average time. More studies are encouraged to find relationships between variables affecting the effectiveness and charging speed of the device.
