This paper introduces a method to control capillary flow rates on nitrocellulose membranes by simply pressing the nitrocellulose membranes using a household laminator. By applying pressure on nitrocellulose membranes, we can easily change the thickness of the nitrocellulose membrane and therefore change the pore size of the porous structure. We also notice that the pressure can break some nitrocellulose fibers. We investigate the influence by measuring the capillary flow rates on nitrocellulose membranes treated by different pressure, and also check their capacity of water absorption. We find that capillary flow rates decrease on nitrocellulose membranes with pressure treatment and the method can reduce the capillary flow rate by up to 42.3%. The water absorption capacity also decreases for nitrocellulose membranes with pressure treatment, and the maximum decrease is 44.6%. This method is promising in reducing the sample flow rates in biosensing devices made of nitrocellulose membranes.","PeriodicalId":142575,"journal":{"name":"2023 IEEE 18th International Conference on Nano/Micro Engineered and Molecular Systems (NEMS)","volume":"10 12","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113990131","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Imagine if touch communication could be realized in non-contact wireless ways just as sight and sound do, there could be a revolutionary change in the way that we feel the world. Here, we developed a haptic interface with self-sensing actuators for wireless touch communication. The flexible self-sensing actuator owns the functions in both tactile sensing and haptic feedback. When this soft haptic interface is conformally worn on the skin and dynamically pressed, the actuators on the interface will generate a response sensing voltage as tactile signal. When the actuator is actuated by an alternating voltage, the magnet in the actuator will generate a mechanical vibration as the haptic feedback. Via wireless Bluetooth transmission, one haptic interface could receive the tactile signal from the other haptic interface and then run synchronized haptic feedback. Thus, the touch communication is realized between two users in bidirectional way. This wireless touch communication also makes remote touch video possible, which will greatly enrich human social experience and shorten the social distance.","PeriodicalId":142575,"journal":{"name":"2023 IEEE 18th International Conference on Nano/Micro Engineered and Molecular Systems (NEMS)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114832091","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many flexible sensors have been developed in the past decade attempting to improve and digitize Traditional Chinese Medicine Pulse Sphygmopalpation (TCMPS) data. Typically, TCM doctors use their fingers to obtain physiological information from the wrist radial artery and determine a patient’s physical condition by sensing temporal and spatial information of the pulse waves. However, an important element in the TCMPS method is that the fingertips must apply three different pressure levels onto a patient’s wrist in order to properly obtain the wave patterns described by TCM doctors. Unfortunately, past work failed at addressing this fundamental problem for TCMPS – existing flexible sensors have not reported the capability of measuring the truly applied pressure onto a patient’s skin while measuring temporal variations of the pulse waves. We present here a method that allows TCM doctors to record a patient’s pulse in real-time using a tactile sensor array while the fingertip pressure applied to the skin can also be recorded. We believe our work will significantly advance TCM by providing a repeatable and stable pulse wave collection methodology incorporating the vital concept of sphygmopalpation with variable applied fingertip pressures.","PeriodicalId":142575,"journal":{"name":"2023 IEEE 18th International Conference on Nano/Micro Engineered and Molecular Systems (NEMS)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134240834","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are few studies on the traditional electroplating assisted cathode to improve the thickness uniformity of metal coating, and most of them use a single surrounding structure, which is difficult to adapt to the thickness uniformity improving of thick metal coating in complex microstructure devices. This paper presents a method for improving the uniformity of coating thickness by using complementary auxiliary cathode structure. A cross-shaped on-chip auxiliary cathode structure complementary to the mask pattern is designed to disperse the local over-concentrated current density. At the same time, the annular off-chip auxiliary cathode is combined to improve the uniformity of the same batch and single module at the wafer level and module level. A FEM model is established to optimize the structure, size and position distribution of the auxiliary cathode. The simulation results show that compared with the structure without auxiliary cathode, the uniformity between the components and inside the components of film thickness are improved by 90.1% and 55.9% respectively. This is of great significance to ensure the processing consistency and performance stability of thick metal film microstructure devices.","PeriodicalId":142575,"journal":{"name":"2023 IEEE 18th International Conference on Nano/Micro Engineered and Molecular Systems (NEMS)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129549451","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, commonly used methods for lower-limb motion detection, such as inertial measurement units (IMUs) and motion capture systems, have limitations such as drift and high cost. To address these issues, we developed a wearable kneepad sensor using textile resistive strain sensors to measure knee angle during lower-limb motion. The strain sensors change in resistance signals caused by their deformation of them when the knee joint bends. To improve the accuracy of knee angle measurements, an encoder was integrated with kneepad sensor onto a prosthetic limb and used linear mapping method to calibrate the kneepad sensor with the encoder data as the ground truth. The calibrated kneepad sensor achieved an R$^{2}$ value of 0.956, MAE of 6.15°, and MSE of 64.35 while detecting the knee angle. It was demonstrated that the ability of the kneepad sensor to measure knee angles during two types of lower-limb motions, sit-to-stand (STS) and knee extension. It is shown in this work that this comfortable, wearable kneepad sensor can help detect knee angles during lower-limb motions in various environments and has broad applications in healthcare and robotics.","PeriodicalId":142575,"journal":{"name":"2023 IEEE 18th International Conference on Nano/Micro Engineered and Molecular Systems (NEMS)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123503191","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
