Background: Alzheimer's disease (AD) affects over 55 million people worldwide and is characterized by abnormal deposition of amyloid-β and tau in the brain causing neuronal damage and disrupting transmission within brain circuits. Episodic memory loss, executive deficits, and depression are common symptoms arising from altered function in spatially distinct brain circuits that greatly contribute to disability. Transcranial electrical stimulation (tES) can target these circuits and has shown promise to relieve specific symptoms.

Background: Effect of dynamic lighting on sleep were studied since 1980's. Traditional light sources were used due to lack of advancement in technology and also researchers assumed illuminance as cause of melatonin suppression. This led researchers to use high illuminance to suppress melatonin at day time.

Background: When it comes to reducing children's fear, anxiety, and discomfort during dental procedures, substantial local anesthetic delivery promotes adequate intervention. In the dental operatory, local anesthetic injections are the most anticipated or feared stimuli. The application of topical anesthetics, cryotherapy, and transcutaneous electrical nerve stimulation (TENS) to the oral mucosa prior to local anesthetic injections can alter pain perception in children.

The integration of flexible electronics and photonics has the potential to create revolutionary technologies, yet it has been challenging to marry electronic and photonic components on a single polymer device, especially through high-volume manufacturing. Here, we present a robust, chiplet-level heterogeneous integration of polymer-based circuits (CHIP), where several post-fabricated, ultrathin, polymer electronic, and optoelectronic chiplets are vertically bonded into one single chip at room temperature and then shaped into application-specific form factors with monolithic Input/Output (I/O). As a demonstration, we applied this process and developed a flexible 3D-integrated optrode with high-density arrays of microelectrodes for electrical recording and micro light-emitting diodes (μLEDs) for optogenetic stimulation while with unprecedented integration of additional temperature sensors for bio-safe operations and shielding designs for optoelectronic artifact prevention.
