| dc.description.abstract | 我們提出了一種新穎的觸覺感測機制，利用粗糙表面的接觸電阻，在承受壓力時，兩個接觸面積變化而導致接觸電阻變化來求得壓力的數值。相對於傳統電阻式觸覺感測機制主要利用壓阻現象，而導致靈敏度受限制，我們的方法可以藉由感測接觸結構的少量變化，可提升感測器靈敏度。
此感測機制可利用於纖維布的基板上，並且使用銀為線路區域和石墨烯油墨為感測區域的兩階段網版印刷。同時，製作了三種不同導電材料組合的觸覺感測器，使其具有不同的表面粗糙度，其導電電阻分布，來最佳化這些變數對於感測器靈敏度的影響。結果發現，利用石墨烯油墨感測區表面，具有微尺度的柱狀結構，加上了玻璃纖維布基板的可壓縮性，感測器在低壓力的區域（<1 kPa-1）中有1 kPa-1 的靈敏度。 我們的觸覺感測器具有低成本，易於製造、可穿戴等優點。同時，我們利用了藍芽無線模塊和信號處理電路量測到人體的脈搏資訊的應用，另外也展示了感測器陣列在電子皮膚中的應用。而這些成果證明了我們所開發的穿戴式觸覺感測器在健康監測的應用上深具潛力。 | zh_TW |
| dc.description.abstract | A wearable tactile device on fabrics based on Electrical Contact Resistance (ECR) variation mechanism is developed for the first time. The proposed device consists of one top and one bottom substrates, which are screen-printed with conductive materials then faced-to-face assembled. Due to its exclusive features of surface roughness and material compressibility, the fabric substrate is favorable in ECR variation mechanism. The device is optimized with different conductive materials to create more pillars and further enhance the device sensitivities. Device characteristics and practical applications are investigated in monitoring human wrist pulses with wireless module and smartphone, showing its capability in fast response and high sensitivity for internet-of-thing and medical applications. | en |
