“…Stretchable ceramics such as buckled lead zirconium titanate (PZT) ribbons [27] and buckled and serpentine zinc oxide (ZnO) ribbons [28] are popular materials for biomechanical energy harvesting applications attributing to their superior piezoelectric properties compared to organic piezoelectric materials [29]. However, up to now, ceramic serpentine ribbons are far less used than metal serpentines, due to their challenging fabrication processes and less understood mechanical behaviors.…”

“…Piezoelectricity is a physical phenomenon that converts mechanical deformation into electricity and vice versa [19]. Thus, materials can be designed to be interfaced with soft tissues and monitor biological forces [20] or can generate electricity from mechanical deformation and used as self-powered force sensors. Unfortunately, the most commonly used piezoelectric materials such as lead zirconate titanate and polyvinylidene difluoride cannot be implanted into the human body due to their intrinsic toxicity or nonbiodegradable structure.…”

Manual and mechanical suturing are currently the gold standard for bowel anastomosis. If tissue approximation fails, anastomotic leaks occur. Anastomotic leaks may have catastrophic consequences. The development of a fully absorbable, biocompatible sealant material based on a bio-ink silk fibroin can reduce the chance of anastomotic leaks. We have produced a Ca-modified plasticised regenerated silk (RS) with gold nanorods sealant. This sealant was applied to anastomosed porcine intestine. Water absorption from wet tissue substrate applied compressive strains on hybrid RS films. This compression results in a sealant effect on anastomosis. The increased toughness of the hybrid plasticised RS resulted in the designing of a bio-film with superior elongation at break (i.e., ≈200%) and bursting pressure. We have also reported structure-dependent piezoelectricity of the RS film that shows a piezoelectric effect out of the plane. We hope that in the future, bowel anastomosis can be simplified by providing a multifunctional bio-film that makes feasible the mechanical tissue joint without the need for specific tools and could be used in piezoelectric sealant heads.

“…Piezoelectric materials are often used for force/pressure sensors, transducers, and generators (10,11). The materials can even be fabricated into nano-and microstructures and interfaced with soft tissues to monitor biological forces (9,(12)(13)(14). Since piezoelectric materials can generate electricity from mechanical impact (14), they can serve as appealing sensing materials, alternative to the described passive semiconductors and capacitive polymers, for self-powered force sensors.…”

Measuring vital physiological pressures is important for monitoring health status, preventing the buildup of dangerous internal forces in impaired organs, and enabling novel approaches of using mechanical stimulation for tissue regeneration. Pressure sensors are often required to be implanted and directly integrated with native soft biological systems. Therefore, the devices should be flexible and at the same time biodegradable to avoid invasive removal surgery that can damage directly interfaced tissues. Despite recent achievements in degradable electronic devices, there is still a tremendous need to develop a force sensor which only relies on safe medical materials and requires no complex fabrication process to provide accurate information on important biophysiological forces. Here, we present a strategy for material processing, electromechanical analysis, device fabrication, and assessment of a piezoelectric Poly-l-lactide (PLLA) polymer to create a biodegradable, biocompatible piezoelectric force sensor, which only employs medical materials used commonly in Food and Drug Administration-approved implants, for the monitoring of biological forces. We show the sensor can precisely measure pressures in a wide range of 0-18 kPa and sustain a reliable performance for a period of 4 d in an aqueous environment. We also demonstrate this PLLA piezoelectric sensor can be implanted inside the abdominal cavity of a mouse to monitor the pressure of diaphragmatic contraction. This piezoelectric sensor offers an appealing alternative to present biodegradable electronic devices for the monitoring of intraorgan pressures. The sensor can be integrated with tissues and organs, forming self-sensing bionic systems to enable many exciting applications in regenerative medicine, drug delivery, and medical devices.
