Peltier modules array on common alumina substrate for the blind - thermal and electrical tests

摘要

The paper presents the thermal prosthesis for the blind people. Peltier micro-modules are soldered to the alumina substrate with screen printed connections. Featured solution enables accelerating the work of the device, better temperature stabilization of the touched Peltier micro-module, more accurate thermal visualization and higher mechanical strength. Electrical and thermal test results enable choosing optimal power supply voltage for Peltier micro-pumps.
