DustNet: A Wireless, Battery-Free, Sub-mm Scale Neural Recording Implant Network

The most commonly used method for in situ neural interfaces involves implantation of micro-electrodes on deeply-seated nerves that are connected to
an external device, using transdermal wires, which performs recording and decoding of neural data to infer intention. The tethered nature of this method
results in a relatively short implant lifetime (a few weeks) due to infection, displacement of the implanted electrodes caused by externally applied force
on the wires and...

Coherent Silicon Photonic Links for Datacenter Applications

With the growing appetite for compute-intensive AI applications, data centers continue to push for high-bandwidth compute solutions. Such systems demand high-speed I/O. Traditional data center interconnects, such as Ethernet, have continued their march towards exponentially higher data rates to meet this demand. This protocol is realized with servers using optical fibers to communicate between one switch ASIC chip to another. The bottleneck here is "the last electrical mile". Historically, a switch ASIC...

A Wireless, Implantable, Multi-Color Fluorescence Image Sensor for Monitoring Response to Cancer Therapy

Implantable sensors capable of real-time monitoring of complex cellular dynamics can provide critical information for understanding disease progression and treatment response, leading to more personalized medicine. An impactful application is in cancer immunotherapy which produces durable responses but suffers from low response rates (<50%). Multicolor fluorescence microscopy is a critical tool for the study of multi-cell type dynamics but limited optical...
