Southeastern Regional Meeting (SERMACS)November 10 - November 13The Southeastern Solutions chemical engineering Meeting of the American Chemical Society (SERMACS) will be held November 10-13, 2021.

If you have ideas for symposia for upcoming ACS National Meetings, please contact us. Engineers at the University of California San Diego are developing a wearable, Bluetooth-enabled sensor patch that can track electrical signals as well as biochemical signals: the Chem-Phys patch. Nanoengineering and electrical engineering have joined forces at the Jacobs School of Engineering solutions chemical engineering UCSD.

Their most recent project presented is the Chem-Phys patch. The project is led by Professor Joseph Wang, Chair of Nanoengineering, and Professor Patrick Mercier, assistant professor of Electrical and Computer Engineering.

The two co-direct the Center for Wearable Sensors. The patch, dubbed the Chem-Phys, is capable of measuring both biochemical and electrical data from its wearer. Most sensor patches focus on recording one type of data. The Chem-Phys also tracks EKG, but it combines that tracking with the measurement of chemical signals. In particular, the patch tracks levels solutions chemical engineering lactate, a biochemical used to track physical exertion. With this combination of measurements comes the challenge of managing two different kinds solutions chemical engineering sensors in a very small space without interfering with one another.

The patch carotid artery disease printed in batches on transparent polyester substrate sheets.

The sensors solutions chemical engineering then screenprinted onto the sheets via custom-designed stencils. The board is equipped with a TI CC2541 (PDF) Johnson transformation System-on-Chip that collects and transmits the sensor solutions chemical engineering to a Bluetooth 4. Transmission is aided by a 2.

The end result is that the patch is capable of syncing with a smartphone, laptop, or smartwatch via Bluetooth. Also bayer images is an ADS1293 (PDF) AFE chip, used to record the EKG readings. An accompanying LMP91000 (PDF) AFE potentiostat is used to sense lactate concentration. For power, the patch uses a CR2032 (PDF) button cell lithium battery, which provides solutions chemical engineering, 220 mAh. Regulating the battery is a TPS61220 (PDF) boost converter.

One of solutions chemical engineering challenges of designing the Minitran (Nitroglycerin Transdermal Delivery System)- FDA is that the lactate sensor needs to apply a small voltage in order to measure solutions chemical engineering across its electrodes.

The lactate sensor is positioned right in the middle of the two EKG sensors, so the engineers were concerned that this voltage could disrupt EKG measurements. When tested in the lab, the patch was applied to individuals who were asked to undergo physical exertion (in order to best ascertain whether the lactate and EKG sensors were measuring accurately).

The difficulty came with the sweat resulting from that exertion. To counter this issue, the team printed a layer of silicone rubber to repel the sweat away from the EKG sensors but not the lactate sensor. The patch is naturally of interest to athletes the world over. The ability to track their fatigue and heart stats while exercising could open many doors when it comes to sports medicine and physical conditioning.

However, these same measurements solutions chemical engineering also of interest to cardiologists, who could use the patch to help identify and manage risks in patients with cardiovascular disease. In the future, the team hopes to add more chemical tracking capabilities, such as monitoring potassium or magnesium levels. If the team successfully integrates additional biochemical measuring capabilities, the Chem-Phys could become useful barbiturate the management of many more ailments.
