When a person suffers from an injury, there are specific methods of treatment which are recommended according to the type of injury. One of these methods involves Cryotherapy, in which the part of the affected body is exposed to cooling for decreasing the temperature. The aim of this therapeutic method is to decrease cellular metabolism, increase cellular survival, decrease inflammation and reduce pain and spasm.  The system designed in the present study involves the possibility of “smart†treatment using portable thermoelectric cooling devices based on electronic hardware, software and digital control techniques. In the proposed system, all stages of treatment have been performed automatically by using Arduino as the microcontroller to controlling temperature in cryotherapy methods. This research focus on usage of thermoelectric effect with Peltier module for smart electronic cooling and does not involve the usage of chemicals or cooling materials e.g. ice. Smart cooling methods have significant advantages that they are highly accurate and allow precise timing of the treatment especially for the athletes, and for whom the recovery time from injuries is critical. This approach can be fundamentally important for practical investigations relating to the timing of cryotherapy for any type of users.

ABSTRAK: Apabila seseorang mengalami kecederaan, terdapat kaedah rawatan khas yang disyorkan berdasarkan jenis kecederaan. Salah satu kaedah ini melibatkan Krioterapi, di mana sebahagian kawasan badan yang terlibat didedahkan kepada kesejukan untuk megurangkan suhu badan. Tujuan kaedah terapeutik ini adalah bagi mengurangkan metabolisme sel, menambah sel selamat, mengurangkan radang dan mengurangkan sakit dan sentakan. Sistem yang direka dalam kajian ini berkemungkinan melibatkan rawatan bijak yang menggunakan alat penyejuk termoelektrik mudah alih melibatkan peranti elektronik, perisian dan teknik kawalan digital. Dalam sistem cadangan ini, kesemua peringkat rawatan telah dilaksanakan secara automatik menggunakan Arduino sebagai alat mikro-kawalan bagi mengawal suhu dalam kaedah Krioterapi. Fokus kajian ini adalah dengan menggunakan kesan termo-elektrik dengan modul Peltier untuk penyejuk elektronik bijak dan tidak melibatkan penggunaan bahan kimia dan bahan penyejuk seperti ais. Kaedah penyejuk bijak ini mempunyai faedah ketara seperti sangat tepat dan memberi masa rawatan yang jitu terutama untuk atlet, dan kepada sesiapa yang tempoh masa pemulihan kecederaan amat penting untuknya. Pendekatan ini boleh menjadi asas penting bagi penyelidikan praktikal berkaitan masa krioterapi untuk pelbagai jenis pengguna.
