提出了一种以多壁碳纳米管(MWCNTs)为导电填料，以天然纤维素超细纤维(NCMF)和聚二甲基硅氧烷(PDMS)为基材的柔性混合压电发电机(HPG)，避免了对纤维进行进一步的化学处理和传统的电极化产生压电电压的步骤。它提供了高的电气吞吐量，在反复手动冲压下，开路电压类似于30V，功率密度类似于9.0微瓦/厘米(3)。我们演示了如何通过HPG为各种便携式电子设备通电。因为纤维素是一种生物相容材料，这表明HPG在生物医学应用中可能有更大的潜力，例如人体内植入的电源。
A flexible hybrid piezoelectric generator (HPG) based on native cellulose microfiber (NCMF) and polydimethylsiloxane (PDMS) with multi wall carbon nanotubes (MWCNTs) as conducting filler is presented where the further chemical treatment of the cellulose and traditional electrical poling steps for piezoelectric voltage generation is avoided. It delivers a high electrical throughput that is an open circuit voltage of similar to 30 V and power density similar to 9.0 mu W/cm(3) under repeated hand punching. We demonstrate to power up various portable electronic units by HPG. Because cellulose is a biocompatible material, suggesting that HPG may have greater potential in biomedical applications such as implantable power source in human body.
