Abstract: A design method of an assistive device and an electronic system of assistive device design are provided. The design method of the assistive device are adapted for an electronic devices including a processor. The design method includes: obtaining a point cloud data of a limb part; determining a plurality of reference cross sections according to the point cloud data, wherein each of the reference cross sections is determined corresponding to bone protrusion feature points of the point cloud data, wherein the bone protrusion feature points are corresponding to the bony prominences of the limb parts respectively; establishing an initial digital model of the assistive device according to the reference cross sections; and performing a structural simulation analysis according to the initial digital model and design limitations to obtain a product digital model of the assistive device.

Abstract: A thermoelectric module including at least one PN junction device is provided. The PN junction device includes a PN junction structure, top electrodes and at least one bottom electrode. The PN junction structure includes an N-type thermoelectric element and a P-type thermoelectric element, wherein side surfaces of the N-type thermoelectric element and the P-type thermoelectric element facing each other are in contact. The top electrodes are separated from each other and respectively cover a portion of a top surface of the N-type thermoelectric element or a portion of a top surface of the P-type thermoelectric element. The bottom electrode covers a bottom surface of the N-type thermoelectric element and a bottom surface of the P-type thermoelectric element.
